Some idea for "Thanks"

people spam thanks because they think their number of total comments actually matter

-Edit- and i agree, a thumbs up button or something similar would be a good alternative

Yeah ditto, seeing Thanks button and then adding a list of users that "Thanked" (if it matters for gifter) him and leaving comment section free of thanks for actual questions and comments.
I support this suggestion (even though it was suggested a lot) and it has my vote.

Use this: SteamGifts.com Thank Filter :)

A nice idea but people would still write thank you in the comment section because they are dumb

Old idea from a new user

What for me, "thanks for opportunity" goes without saying, and "thanks from winner" is of great matter .)

Hint: there's a search function

In some group's rules, is required that you comment in every of its giveaways.

Do people get mad if they hold a door for someone and aren't thanked profusely for their extreme generosity? Seriously, that shit is more annoying than letting the door smack them in the face-- what's the point of being nice if you're only in it for the gratitude? >__<
