EDIT: Read The Updated Description:

Sure, I'll spend it on your mom.

Sorry... I didn't realize this was such a valuable game. I also didn't realize the blacklist had a limit.

I'm not blacklisting anyone, so you can join if the giveaway didn't end yet by the time you read this.

Sorry, again.

You can join now, I'm not blacklisting anyone. See the updated description.

Or people that will read it and enter anyway. I did pick up a new BL, but not from this account. So multi-accounter, or someone else using their entries to BL?

a large chunk of it will be people to lazy to read descriptions, or those using esgst 1 click enter(this isn't autio joining... its just removing the load page in separate tab step) without the popup description feature on.

not really worth blacklisting those under a certain level either, just level gate them out of giveaways, many be will be 0-3 as a minor investment for freebies.

also find it funny someone blacklisted the creator of this in advance... when they don't really make giveaways themselves.
that green enter button keeps taunting me and my 400p >>

There are 1000 places in the blacklist

I didn't know that!!!

The more I read the comments the more I think I made a huge mistake. Oh, well...

After reading the comments here, I realized I made the giveaway on bad assumptions. I won't blacklist anyone now, and I updated the description. Check it out.

Thank you man.

I would advice you to set a minimum level for public GAs. My choice for own public GAs is level 5 because my BL is full with "only" level 5 or higher accounts. So i recommend at least level 3 or 4.
On top checking the winners with https://www.sgtools.info/activation and report the ones that have unactivated wins is always helpful.

With this way you will have a lot on your BL from the ones that entered this GA, without to write something in the comments that show that they are real people, but i think your BL will not be full.
So you would hit both targets that you have now (combat the autojoiners and don't add so many that your BL isn't big enough).

The next GA, with level restriction, bring then not so many new ones for the BL and it will be lesser work to add them as now.
So only one time (now) much checking needed.

A other approach is to create a GA and write in the description of this GA then the link to a other GA (prefered the same game), then you see how many don't read descriptions and it reward the ones that read descriptions with much better winning chances.
When you have more as one copy of a game, is this the best solution.
When you have only one key for each game, it is more difficult because someone could have the first game and will never see the description, with the second GA link, for it because it is hidden for him.

Or you join groups that control which users join their group and kick the ones that break sg rules.
It doesn't give much of such groups (the most groups don't care) but as example the groups from Metalhead8489 and my own are such ones.

I hope you find a way that fit for you.

End don't justifies the means, in this case. I see that even many people that are very active in the forums, even big gifters and moderators came here to talk about the situation.

But, hey, live and learn. Anyway, thank you for rethinking your methods and your position. Take it easy, mate! =)
