What's the stupidest mistake you've made in here?

When I first joined I created a few giveaways for games I thought I had keys for...but they were typically "bugged" shown as not yet redeemed when they had already been. So I had people super angry at me that I gave them false hope, and then gave the mistake of giving different keys as a consolation prize through steam messages (after deleting the giveaways), since they swore at me and hated me anyways.

Hopefully the winner enjoys and appreciates both games, mistakes happen I'm sure most would understand. :)

It was mistake to create here giveaways

I won Bad Rats. I'll never be able to delete it from my Steam account.

Uh, well, hard to say.
Maybe not being appreciative enough of the community in general?
Because a lot of people here really seem to care, are pretty involved and seem to always try their best etc.
And I like that, to be honest..

I did the most obvious mistake. I wanted to make my very first giveaway for a game that was given previously for free (and which I had no knowledge of)... what do you do when you cannot choose the proper game in the list? Of course. You choose a different version of it. I was really nice however. I stated so in the giveaway description. It did not take long before I realised my mistake but it still landed me 5 nice blacklists. I learned the hard way but I think I have come a long way since then :)

Have made quite a few blunders...think the worst was putting up a quick one hour giveaway for Hellphobia. The key was from an Indiegala bundle and I had activated a few of the games on my account already. After posting the giveawy on Sg for Hellphobia I went back to the IG site and decided to keep the last game in the bundle for myself. Activated the key to my account...and it was for Hellphobia (stupid noob copy/paste error :(
Just deleted the SG giveaway. Hopefully no one noticed.

Refusing to say no to a guy that kept pushing I take a game, even though I had won it a day earlier. I had no idea about re-rolling back then. It was the Payday Christmas soundtrack.

Leeching often because I'm worried about giving away an already used or wrong key and having to buy an extra copy or getting my account perma-banned. This is why I tend to just give my keys to close friends that I know will play and appreciate them. I know that some people enter giveaways that they REALLY want to win, but I enter giveaways because even if I win a game that is bad, I'll still give it some of my time and leave a review for it once I get to it. In fact, I'm actually going to start plowing through a majority of my won giveaways this week, since I feel like a piece of shit for not playing them sooner. Sorry if I haven't played your game that I won yet. I've put over 200 so far in my #NeverPlayAgain category and I'm just using a random generator, until recently when I kept getting the same games over and over again.

A guy gave me the wrong key to a game, but I had already marked it as received before I checked it because I figured nothing would go wrong since he was such a low level. I recently obtained a copy of the game that I accidentally marked received. Does this remove the mark from my account?

The worst one was when I gave away a game that I had obtained through G2A's multi-buy key bundles(I only bought it once because I realized how dumb it was a tad bit too late). The guy ended up trying to re-gift it and ended up getting a perma-ban.

My mistakes happened quite early in my account, but they have really messed with me, especially for SGTools giveaways. I have no contact at all with the guy who gave me the Payday 2 gift and it seems like he doesn't get on often, so I can't return it.

I know that many people don't or won't agree with me on multiple topics on this site, but I try to make the best of everything and do my best to see all sides to a story or argument. Sorry if I've ever upset you or seemed like a general asshole. Have a happy holidays everybody.

I waited for 2 weeks patiently after winning a giveaway and didn't hear nothing so mark it as un-received.
Then a week later checking the GA creator's details decided to check my spam folder that i haven't checked for months just in case and found the gift email.
There was no mention in the GA description but I felt so bad, so i activated, marked as received and contacted the giveaway creator to personally say sorry and i gifted him a nice game from his wishlist.

Entering giveaways for games I didn't want just to make sure it got 5 entries (group)
Entering everything I could (when I first joined)
Creating Humble Gift links 4 weeks before the giveaway was set to end. (4 weeks ago)

Speaking my mind on threads. Sometimes I agreed, sometimes I disagreed. No matter what you do, there will always be some fragile souls that blacklist you for not agreeing with them :/
I don't even care for the blacklist itself, I just don't want someone to hold a grudge against me because I said that "X was overrated" or "I agree with you"

Here? Nothing... on a different similar yet different site? Yes.

I let the winner chose a game. Anything $2.50 and under. The winner tried to talk me into a $5 game. It resulted in a painful 2 week exchange with the person before he finally agreed to something.

Redeeming a won game on my 2nd account. I think I did that about 5 times and it will happen again I'm sure.
Had to buy or trade the games to keep a clean slate

Trading keys with a SG friend while I was drunk and mistakenly gave a 50$ game instead of a 0.10$ bundle game.

Once I activated the key I won on wrong (alt) account, and had to buy the bundle to activate the game on my main. Felt really stupid, but at least bundle was still sold, so I only lost money. Now I'm extra carefull when it comes to activating my wins.
And once I made a giveaway for a key from gamersgate, thinking it was regionlock-free, and it happened to be locked to my country. I felt stupid. Game still had discount, and I tried to buy it again but send via gamersgate gifting system (winner was kind enough to cooperate). And it didn't worked too! I felt double stupid. We both wrote to gamersgate support, and luckily they were able (and willing) to help, so the winner got his prize after all. Since then if I do giveaways with keys from gamersgate, I put a regionlock - just in case.

i begged and made a giveaway with an expireed key...

Registering with my MMO name (and then being too lazy to change it).
Now I'm just kinda stuck with it. :3

I once made the stupid mistake of creating a giveaway for a game when I had not bought the key yet. I ended up forgetting and missed the deal, so I had to buy the game at full value, and it was not a cheap game. :/
