I can't understand...

For the lols.

because no-one reads anything more than the title and the big green button.

Don't have anything better to do with points.

Many people enter every giveaway they see without reading descriptions, they just want to win games. Some people also just want to store their points in them and get them back later but there are many idiots that even post "thanks" comments on these giveaways.

BTW "warning" other users by posting "this giveaway is fake" or "REPORTED" is not allowed and you can report them also.

Check profiles of those illiterate people who thank on such giveaways. Probably a vast majority of them are either from the US (books? edible? no? gtfo) or Russia (books? don't call me names!). Sorry, I had to :D

As a method to store points.

bots

If I win it, no one else has to deal with the obvious disappointment that comes after it. Also, those giveaways usually have thousands of entries and I like to beat the odds.

because they enter it and immediately rush to go thx like a bunch of idiots

Because maybe it's not!
