Is it okay to blacklist winner who doesn't have courtesy to say thank you?

I would not, but I would not judge one who would do that either....

You are free to do what you want, since 75% don't say thanks your list will be pretty full soon.

If I have given non Bundle giveaway and winner hasn't even said "thank you" I auto blacklist him.
But this situation never happend to me, cuz I am giving it to groups and people who really appreciate chance to play it

I think it's okay to do so - even if I don't blacklist because of that reason myself.
I personally leave a thanks for every game I won. That's the least I can do to show my gratitude.

It's totally your choice and prerogative and you can do so, or not, at your own leisure. ^^

Blacklisting is not against the SG rules. ;-)

My vote goes for "No", I appreciate the kind words you've used, tho. This happens IRL, too... and you don't have a blacklist there... :D
When this happens to me, I just move on cause SG (and the world) is plenty of beautiful people!

I don't do it, but why not I guess. Some GA makers actually require winners not to say thank you, so I can understand maybe some winners don't say it for that reason.
As a rule of thumb, I always say thank you unless:
1) GA creator requested not to do so or
2) GA has many winners (say, more than 10-ish), because then it feels a bit like spam

I think it's a valid reason, I appreciate thanks from the winner unless it's 10+ copy giveaway and thank every one I receive a gift from.
I usually don't blacklist people myself unless they are someone that I don't want to have anything to do with or high level rule breakers. I have 11 people there atm.

Do what you want, don't be a sheep but in the end, blacklist is as pointless as an appendix, and frankly my dear, nobody gives a damn.

At the beginning i made free for all GA's i had there 90% leechers that don't know at least a thanks. All are blacklisted.
Later i made groups (not sg groups i mean steam groups) GA's and have around 50% Leecher and around 60% that don't know a thanks. All blacklisted with 1 exception (he was first 3 weeks at SG...).
All this guys not set the recieved hook fast too ... often it takes 1 week or longer. Very frustrating when you start and have only 2 or 3 GA spaces.
After that i secured my GA's with sgtools and own rules against leechers. Since this time each winner know a thanks and i meet a lot of nice people as winners of my GA's too ;o)

Before i give anything to anyone that not know a short thanks i will throw it in the trash.

I am too old to support such bad behavior :DDDD

It's ok to blacklist anyone, even random people. It's your list.

The problem is, that you can be blacklisted for whatever reason.

You like vegetables? Blacklist.
You wear glasses? Blacklist.
You like Potatoes? Blacklist!

I think that's okay. I always thank to the giveaway creator when I win. I respect them and their effort cause not everybody does like to give something to people they don't even know. I would blacklist the people who don't say thanks but I'm too lazy 😄

out of curiosity, can you check in a day or so on how many blacklists you've been added since creating this thread?

Speaking of Fyantastic's thread, saying 'thanks' at any time, especially before gifter sent anything, guarantees as a solid sidenote, that winner is aware of win and is ready to receive the gift.

You can't require anything though, and can add to BL these rude users who can't care even to thank you.
Sad thing would happen when you will realize that you add to BL too big fraction of users who won something from you. Does it make the rest who haven't yet win anything from you better? Of course not, but at least they haven't yet fail your 'trial'. So any decision can be well justified depending on what is more important to inner yourself. And this is revertible, so experiment as you like <3

It is still amazing how rude and irresponsible people are. Good that mostly - passively, not saying a couple of pejorative words to every gifter they received a present from :) For example "Oh god why I won this shit instead of something more expensive, you greedy .." instead of "Thanks". This would be hilarious <3

Existing of CV has a real backfire effect. Probably a lot of users think that since gifters get CV and levels, they are not doing gifting for any other reason than getting CV, so there is no need to be friendly and even say thanks, not even to think of playing wins etc. And it boils down to winners and participants often not caring who is the gifter (someone faceless), not understanding that gifting spends money, time, efforts etc. CV is just a system of approximate recording of investment of users. There is nothing special on higher levers, at least definitely nothing worth spending anything specially to get here. Best games are most frequently given either as public low lvl or group giveaways + may be invite GA from forum, also low lvl and may be WL
Mythical value of CV and levels is something created by users and further reinforced my users themselves, who create these high-level GAs (either experimenting or having wrong expectations, so it is extremely rare).

About every gift, here can be said "it is not to share but to gain profit in the future". Popular stereotype. Every stereotype is a small defeat of reason.

Definitely "No" for me, when I give I don't expect anything from the winner in return

Honestly, I don't blacklist for not saying Thanks, I honestly don't care.

But to each their own, if you want them to say Thanks, then put it in the description of the giveaway. If they won the giveaway, they at least owe you the service of reading your description.

But just mindlessly saying Thanks, I wouldn't care much about it because the Thanks you do get from your giveaways there is a decent chance that they didn't even put it as I have seen scripts that will do that for them automatically too.

You want them to show some courtesy for winning, put in the description that the winner has to post something other than thank you.

I have done that before and had the people who entered say "Moo" instead just to see how many entered and just mindlessly said thanks, entered and mindlessly said nothing and how many actually cared enough to read what I wrote and post.

Yes. It's also okay to blacklist user because you disagree with them. It's okay to blacklist user because they didn't whitelist you. It's okay, because it's your blacklist and your whitelist, and you're free to do as you want with it.

As for the question "Is it okay not to say thanks when winning a giveaway?"
No. It's not okay, it's not polite, and it's disrespectful to the giveaway creator and the Steamgifts community. I'm still willing to excuse it if the key/game was sent via key distributor/email, as new users may not be aware of the possibles workarounds to thanking users without adding them on Steam (my first giveaway won was sent by email, and I wasn't aware I could contact the user to say thanks. Yes, I was dumb and I still am - but now I have knowledge, something new users don't have).

You can blacklist anyone for any reason

I'd never do it, but it's your blacklist and you're allowed to add anybody you want to it for any given reason, or for no reason at all.

honestly, i think that people are blacklisting me when i win their giveaway and i usually type "got the code thank you! have an awesome day or week if its the start of the week or weekend if its weekend and at the end i say Cheers!" idk why but people dont like this xd

depends on the game i'd say
if it's just bundle stuff then i dont really mind per say
but if im giving a pretty good game away, and you cant be bothered to spare the 5 seconds to say a simplistic thank you? it doesnt feel good and i dont feel like the game is going to be played
like im not expecting overwhelming platitudes of gratitude, but it says a lot about you if you dont thank someone for giving you something for free

(the only people i give leeway to are people who are new to the community, like it took me a while before i had the epiphany that I was being rude and should be thanking the creator)
