Guess I'm joining to Comment and like brigade. This ain't reddit, you shouldn't have to have points to give points, to post for points and on and on and on. I wanna see tits, if that means liking the post, fine I'm game, but removing the ability to even do that is dumb.
They did make it worse because outside a few people commenting on threads with "nothing new?" I personally didn't see much spam compared to other sites.
Also the bump features a bigger issue than spam. Be a post 20 days old bumped 10 times a day with nothing new.
