Why do people write 'thank you' in every giveaway?

because its polite to say thank you when someone give you free games.

Thank you for asking this.

Thanks!

Thanks!

You think writing a poem will increase your chance to win?

It's "polite" and it increases your comment count, that's why people also use scripts for that.

It's just one of the things that everybody does because everybody does it, I doubt that even 1% of the people are honestly thanking the giveawayer to have a very small chance to win a game.

If the giveawayer? hasn't asked me a question i always write "Awesome giveaway, sir!" (he says and now everyone starts writing that XD ). Yay i'm different XD !

thank you

Thanks for Skyrim !

Thank you

I don't know.
BTW Thanks

TY!

because saying "f*ck you for this chance" would be to much typing

Thank you for opening my eyes!

Thanks !

No thanks.

It's the thought that counts. In my current giveaway I asked the entries to tell me about something but if I see some people just spamming thanks, it's still good enough for me.

Because it's expected of us and some people pay attention to whether or not you do.

its a good way to show that you appreciate the fact that someone payed for something and you have the chance to enter to get that thing for free. if someone would type more than "Thank you!" it would be a waste of letters

because of increasing comment rate and making yourself look active (some groups want a good comments/entries ratio). Personally i just say thanks if the creator wants it (like "say thanks or i wont give you the game if you win") or when i win (usualy like 3-4 times in steam window and also here).

Thank You

cuz they can

Why do people say "bless you" when someone sneezes?
99.9999% of the time people say 'bless you' when someone sneezes, people need to be more creative.
Saying 'bless you' doesn't increase chance to get into heaven.
I even know language script that automatically add 'gesundheit' every time someone sneezes, even if your not in germany.
