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

Thanks.
You can put the hunble-link directly where the key belongs (here on SG) and the winner will see it just fine.
You can even put them there, when creating a giveaway, since you have to sent it manually anyways.

I once did a keydrop without mentioning the game. Unfortunately it was for an unbundled AAA game and the person who took it felt bad because it wasn't their kind of game at all.

I no longer do nameless keydrops, since the last thing I want is to make people unhappy with gifts.

When I was new I made a couple of giveaways for my spare keys and didn't know I had to check if they weren't allowed to be given away, so like one of them of course wasn't and I didn't manage to figure out how to delete giveaways in time and got myself a supsension. Also +1 to entering every single giveaway without liking the game expecting not to win anything at all, luckily most of my early wins were still pretty nice games.

Also made the mistake of blacklisting an entitled user who made a tantrum threads about it yet couldn't find the time to play their wins :3

I sent the wrong key to a winner. It was right above the proper key in my Indigala list, I just copied the wrong one by mistake. I tried to remedy it by contacting the guy on Steam but he wouldn't answer my friend request. Had to sit for a week-long ban because of it.

Activated a won key on the wrong steam account (my brothers). Had to buy the game myself then.
There's worse.

Yup same as you. Lol

giving away games

Voicing my opinions.

make a giveaway from demo keys and think i would make it surpeice for the winners coz im giving away a different games (a very good Games) and god suspended... wkwkwk -_-

Won a game, it was region locked and i couldn't activate it.
Talked with the GA-Creater but he could not talk english...
Gave the game away to someone who could activate it and stayed with the "one not activated"...
Later i bought the game again.

Also_
"Winning games i had no interest in just for the sake of winning something."

BTW...you don't need to email HB gift links. You can just set up your GA as a "gift" instead of "key," and then after the GA completes, you click on the key field to update it, and then paste in the HB friend link, and then hit send. When the person goes to check their "key," they'll get the HB friend link right inside SG instead and can just follow the process.

got scammed in the trade section, have fun with destiny 2, its bad anyways

my biggest mistake is not remaining with a fake personality to fit in with everyone on sg and groups.

my second biggest mistake was picking fights with idiots.

I entered giveaways made by people from my country and thanked them in English.

My mistake? Pointing out rulebreakers mistakes. Their responses usually frustrates me... and I'm still doing that... Oh, fu*k my sense of justice.

Entering and then winning Dragon's Dogma giveaway. It's the only SG win where I can't get 100% achievement completion :'(

A few months ago I forgot to mark some of my groupees keys as used, so I tried to make a giveaway for them. Naturally, the winners were kinda peeved.
Gave them beta keys for my game instead, though, so I guess it all worked out.

I guess maybe forgetting to remove entries after getting a key elsewhere. I also won a game once and didn't get it for a long time because there was no description stating it wasn't a key or whatever. Randomly had an idea to check my email on like the 5th or 6th day and found the gift link,

Entering for a game my PC was´nt able to handle (and winning it) - MGS Ground Zeroes to be exact.
Drove me mad that the GA maker would think i´d only entered for the +1 on a pricey game :E

While creating a pack of cheap bundled games giveaways, I pasted the key in the description for one of them.
Later, winner added me on steam and told me (nicely) key didn't work - including the reason, he already figured it out.

After laughing at myself and apologizing for being an idiot, I did what was right: bought a single key for the game and sent him. Lol.

I gave away over 100 games before I understood the group, puzzle, invite-only, and whitelist giveaways. I also screwed up a giveaway recently because I unknowingly already had the DLC I won.

Winning game(s) I didn't want because I was happier about winning than asking for a reroll (also I was quite new so I didn't know I can just politely refuse the game)
Expecting people actually entering giveaways for games they want (hoarding or mistakes, like my 1st point)
Mixing up two keys in two or three separate ocassions, but thankfully they got sorted out nicely - had extra copies / friends to help me out.
And a funny self-inflicted calling-out suspension for two days that I was laughing at so hard at the suspension screen because I instantly knew that that was the point the support found my comment :D Totally deserved it, it was just funny because otherwise it had a happy end, then moderation happened. Was uncomfortable to browse the forum in private browsing :P

Making giveaways was the most stupid mistake. Never again.

And guy created a thread basically asking"what should I do with this steam gift?" And I jokily said "you can give it to me :P"(with the smile) and then I told him in the same comment that you can either make a GA, trade it or keep it to yourself.

The mod didn't like my begging joke. Banned for a week. Learned my lesson.
