What do you think about that ?

You should always thank the GA creator if you've won a gift.
It's just good manners and gratitude imho. XD

Different people have different behaviors.

For some " marked as received " also means " Thanks comment " too and for some others just pressing " marked as received " button isn't enough.

Don't think too much about this subject!. :)

Do you think it's "normal" that when people win a gift, they don't say a little thanks/feedback to the creator?
It's common courtesy for me. More often than not, giveaway winners don't bother posting anything at all, which I find rather rude. The winner isn't a 10 y/o kid anymore in most cases, just makes me wonder why their parents haven't taught them any manners. We're not your mom, so we shouldn't be the ones to tell you and give out reminders to thank someone.

It is natural for me to say thanks to someone who gives you something but not for all i guess. I don't get it much in public giveaways. I tried some private ones and number increased.

I always say thank you to the giveaway creator when I win a giveaway here. I don't expect that people do it on my giveaways (and I won't blacklist them if they don't), but it's certainly nice to see that people appreciate it. I once had a person posting on a more than three months old giveaway that they just tried the game with friends and really enjoyed it. I think that was the best kind of feedback that I ever got here :)

The question in the poll and thread aren't correlating. Both of them are yes. Yes, I thank when I win, and yes, it is normal to receive only a few thanks after public GAs. I have put up over 140 keys in the past 20 days and received about 15 thank you messages from winners. And this ratio is rather normal based on my experience.
I have to add that in many cases they are too shy because of not sure even about this one-word English phrase or because what we consider common courtesy is not actually that common around those parts and that is normal for them.

It's inconceivable to not thank someone for a free gift. :O I thought this was a given.

Hm, I must confess, I sometimes forget to say thanks (at first), mainly when I see the new wins in the morning on route to work. I activate and confirm them immediately to the sender does not have to wait, but sometimes I decide to do the "write something and whitelist" later when I have more time... and as we all know, out of sight, out of mind... But I know myself so I usually check up on myself from time to time :)

Although it's common, it's still very disappointing. Especially if someone cannot give much (e.g. is Level 0 or has a bad ratio), the minimum they can do is write "thank you" after winning. In these cases I usually do add them to my blacklist if they don't.

BTW, I always follow up when winner thanks me with something like "Enjoy! :-)" or similar. I just can't help it.

I do, "after " I recieve the key!

When people give you a gift in real life, you thank them. Not so much because of the gift, but because of the gesture, because it means they care about you. On Steamgifts however people don't give you gifts because they care about you, but because the RNG selected you as a winner of the giveaway. Appreciation should go to the RNG, more so than the person.

I think thanking people for creating the giveaway in the first place makes more sense than thanking them for delivering a gift to the person chosen by RNG. Regardless, I always thank the person when I win their giveaway, and since most people don't want to be spammed with "thank you" messages for creating a giveaway I mostly chose not to say anything before winning, unless the giveaway is for a game I'm really excited about.

Even so, I personally do blacklist people who don't thank me for winning my giveaways.

I give people three or more days after they marked their giveaways as received to drop me a note. I even write every of my winners a personal email to their adress they can reply to if they want. If they didn't care to write something small back by then, I go ahead and blacklist them. Just as you I'm finding it rather rude and I prefer not to gift more games to people who find manners or common courtesy unnecessary.
I always thank the people who gift me games - I'm always really excited when the space cate jumps at me. I only enter for games I really want and therefor every win is really really appreciated. I think this excitement and the joy of winning should be shared with the creator. In my experience it can make someones day. I had some lovely encounters only through thanking.

I prefer people not to post generic thanks messages on my giveaways, however once they have won something it takes no effort whatsoever to then go back and post a proper thank you. Those who don't just end up blacklisted and I don't have to worry about them again.

In my opinion I don't really mind.

Usually, if I win a giveaway I will leave a thanks message, one of the reason is that the creator might blacklist me if I don't to be honest.

The truth is, Internet consists of people around the world, with different culture and manner. I've seen some creators who want thanks message and some don't. Some of both even threatened to blacklist if winner/people who join don't do what they write (to my understand, they wrote "you know what happened to people who join and don't say thanks").

It's hard to please everyone.

I love that song. :)

Is it normal that people just accept the games without saying a thing? Seems so to me. Not the courteous thing to do, but normal. Far as I remember that was also the case for the train I made, so it's not limited to public giveaways.

I don't win GA's, so don't normally thank givers except on the rare occasions that I look at the giveaway list and see a game I appreciate seeing, and then thank for giving it.

I always have, only times I haven't is when they email you the key instead of adding you.

I try to do that in the GA comments after I win, though if the game is wanted/rarely seen enough I'd do a preemptive one.

I give away games so that the game will hopefully find a loving home. It's nice to be thanked, but I'm not going to blacklist or get upset if they don't thank me.

It's always nice to receive a thanks from the winner, at least you have the impression that it's appreciated and not simply swallowed away by a silent leecher or bot. I'll for sure give one the day I finally win a GA :p
I don't BL people for it though, tbh I'm more bothered by Lv.0/1 with poor ratios (200+ wins for none or one 0.99$ GA) so I started restricting the entry level of my GAs to 2+

No, I don't think it's "normal", and I blacklist them all.

I tend to give a credit to new users... maybe they didn't figure out that feedback showing some gratitude is very appreciated. I tend to do that because, as myself, probably didn't thank my very first games when I started here...
In the other hand, when it comes to old users, there's no excuses... they know how steamgifts works and they also know where all this games comes from. for old users is a sure damn blacklist.
