Nope

It doesn't, but there's nothing wrong with saying thank you in a GA that you particularly like (just avoid a habit of spamming it in everything you enter).

More like it's annoying cause then people get a lot of notification for the exact same comment written by every one.
Like "Thanks for the chance".

Fortunately no because every one will spam " Thank You ", and the creator will have hundred message at the end ...

You have 1/x chance to win any giveaway you join where x is the number of entrants. Reaching a higher level, getting accepted into groups will let you access giveaways with less entries.

Btw it's also a rule on this site that you have to activate your wins on your own account. It's not allowed to regift them.

Yes, provided your comment makes other people less likely to enter (or even better, leave).
For example one may try posting Zalgo text to fool people into thinking their browser is broken, and they will maybe investigate the Zalgo text pseudo-issue instead of entering the GA, thus ma-the-ma-ti-ca-lly increasing your odds to win !
Don't forget, your mileage may vary.
😁

Patience increases your chances. With time, you're bound to win something. There is also groups and bumping your level up to participate in higher level giveaways (usually have fewer entries).

And don't forget, when someone comment, then people will check the profile of the commenter up and see then maybe stuff like multiaccounting on freebie sites, 100 won : 1 gifted or a lot of other stuff they would maybe don't like.
So it's best to only write thank you when you won and be beside that quiet.

Some people blacklist the people spamming too many comments... So best way to keep chances up is to say nothing, apart when you win...

Or, to be active and contributing on forums for whitelists... You never know...

Writing a comment might very well increase winging chance, but it definetly doesn’t increase your winning chance.
