@Mimilu I'm pretty sure they value "likes" more than repeated requests, since most people don't post, they just lurk and like.

EDIT: Yeah part of his post

If you agree with the item posted by another user, simply giving it a "Like!" on that post will help us see the demand and can help the team to prioritize.
So if you agree with something, just give it a like if it's been posted rather than repeating it again.
