should I care if my giveaway was won by a card farmer?

Well, you are giving away games here, and cannot police every giveaway. Still, if you want, you can try to develop a whitelist and give away such games only to those people, or enter a group with verified users, where this thing is forbidden, or nonexistent. Upping the level requirements on the giveaway could help, but level is not everything. I too have a few wins that I did not play already, but backlog here also :). But generally, I find the site to be not parasitic. Your mileage may vary :)

Easy solution

some people farm the games immediately but still have intent on going back thru and genuinely play them too. ^^

also... "Family Share" xD

edit:

Should I restrict any future giveaway to higher levels only?

those levels can be worse at not playing them, as they tend to have a lot more titles to play.

There are also high level farmer...
You can turn yourself to group as Playing Appreciated and such.

usually i only reserve the good GAs for special occasions and limit the entry to a certain few.
It's sad when u spent on something special only for it to be idled but.... it happens.

Restricting GAs to higher levels won't solve anything, every kind of person is on every kind of level, so even if you made level 10 GAs you'd still run the risk of it going to someone that does not fill your individual criteria.
As Yirg linked above PA group, and in addition Actually Playing Games group, are both decent choices if you want there to be better chances of the game being played. There's several other small groups that are primarily populated by people with similar mindsets but only those two to my knowledge have this specific focus.
Also as psybreeze suggested whitelist can also achieve this effect if you only populate it with such people.
A third solution would be forum giveaways gated behind SGTools with a custom rule that only allows entry if the game is wishlisted before the starting date + the total wishlist is below astronomical amounts.
Otherwise you can only include in the description that you wish only people that intend to play the game to enter and pray they abide by it.

You are kind of expecting too much but you are not being unreasonable. I also am disappointed when I giveaway a game I like to people that just leave it on their backlog and it idle for cards. Also real life, current plays, and other stuff may delay playing your wins... If you give them time maybe your winners will surprise you.

Increasing to higher levels would not do much, I think. From my experience, high level users also tend to have more games and a bigger backlog. Maybe you could try entering groups that require members to play their wins in a certain amount of time or for which not playing wins is considered impolite...

Considering the game that you gave away, I would say that you are not being unreasonable.
On the other hand, you made it public, which means that anyone can win without satisfying any custom requirement other than the level.

Don't get me wrong, public GAs are important and very much in the spirit of giving, but one also must be realistic and change their expectation accordingly...

The solution is either limiting those kind of high profile giveaways to private groups, or do private giveaways behind a Steamgifts Tools wall.

Of course, if everyone only gave away games inside of private groups, it would become a circlejerk for a few chosen ones. Again, public giveaways are part of what makes Steagifts what it is, it's a shame many users enter them indiscriminately.

Also, it's important to remember that people have their own priorities. If the winner just hasn't time to play it, I feel it's totally fine, even if it's months. At the end, when the time is right, they will/may enjoy the game to the fullest.
Your winner unfortunately doesn't seem to fall on this category though...

I've been following winners (not just of my giveaways!) for months now and sadly more than 80% doesn't play the games, some don't even idle them.

Then I realized sometimes it takes me months to play something, and that's with wins having priority over stuff I buy myself... it's not that I don't want to, it's just that stuff happens at work and then there's no time and you're tired and... being a gamer in 30s is hard. Of course, I don't enter lots of giveaways for years now, only if I really want to play something... and even then I think twice and re-check what I've already won and didn't have time to play... and yet it happens that I win a game I wanted for years and I start playing, then have to stop for a while, that break grows longer due to circumstances, then... it's weird to continue and even weirder to start over...

That said, there are people who don't care what they enter for, they just wanna +1 and... well, it's not what I'd like for this website, but it's not against the rules.

tldr; people will be people.

I don't care, unless the user is on my whitelist and if it's a giveaway for a more "premium" game. I'm not a rich person, so when I give out non-bundled stuff etc, I hope it goes to "a good home".

I used to put people on my whitelist just based on good ratios etc, but then I noticed some people didn't actually play any of their games or very few, so now I curate my list more carefully and don't just add people if they have good ratios.
I don't expect them to play the game right away. I don't mind if it takes them years to play it. Hell, it will probably take me years to play everything I've won. I just wish that they will play it and not just farm the cards and forget about it.
I personally don't "farm" any of my games. Even the crappiest looking bundle trash I at least try to play. Sure, sometimes they're such garbage or simply don't even work that I only play them for a minute or two.

There used to be a person on my whitelist that had like 3000 games on their account, but they had only achievements in 2 or 3 games.
Why have thousands of games and not play any of them?! I thought even card farmers played at least some of their games.

You will eventually be so numb about it that your mind develops total apathy towards this behaviour. I just cannot bring myself to even hope any more that no matter what trick I try, the game I sent out will actually be ever played.

I mind it too, especially if I went out of my way to buy a good game. I usually blacklist people who've played like 5% of their wins, but obviously you can't find anyone. Maybe try joining a group that requires the winners to play the games they won?

If that person is farming cards from Life is Strange instead of playing it there is something seriously wrong with him/her.

Hi there. I think the game you have given away must be fabulous. I am pretty sure I was entering your giveaway as well :). It can always happen that your giveaway is won by somebody who does not appreciate it and just wants it for card farming. Here is the solution: If you REALLY wish the game to be played, it is easiest to put it in groups like "Playing Appreciated" or similar ones (there are some around; and no, I am not mentioning this group because I am a member myself, it is just the first one that came to my mind. Feel free to check the forum to find other groups). Sure, this adds some restrictions (actually a lot restrictions), but then your game has to be played.
In general, I would not try to be too sad, since there is no way you can change it now, but to keep in mind that a restriction might help you in the future to achieve your goal (however, I think there will never be a chance of 100%). Another way of not getting unhappy about it, is simply not checking what the winner did with this game.

Either give it to Playing Appreciated, or just wait. When I was idling my library ASF just went through everything, so while everything is idled, I do want to play most of them still. So: I understand your concerns, but 2 days is only 2 days. Most of us is playing something, and not stopping a game in the middle just to start a new (won) one is understandable in my opinion. I personally have to-be-played games from 1-2 years before, just to show that people like me / us do happen :D

I personally don't care. I farm every game (because ASF is so effective), I have a big backlog but I'm intended to play every game won. It'll take time.

But a thing that really bothers me a lot (mostly with high level winners) it's when I check their profile and all the giveaways are group related with 10 or so entries, or absolutely all the giveaways being region restricted.

Since it's very easy to identify who you are talking about I'd rather close this thread. It's fine if you want to discuss topics like this one but try to be more general and do not mention specific users.
