Actually there is proof that exist. Look under all my old posts, and read most the insults I got for my typing, and see how many "LIKES" each post got. Its actually pretty common in forums. It's the high school mantality I was mentioning. If the "popular" thing is to insult a person with a mental disability. People will, thinking it is cool and will make them popular.

On one forum last year, I forget which mmo it was for, I posted a comment which I agree'd with what the majority stated. Said posters i agree'ed with then started to pick on me because of my typing. It happens on the W.o.W forums as well as Aion.
This is what forums turned into. They USED to be a way for players to make connections outside of the game.

As I stated as long as we keep out personal like or dislike of the poster, I see no issue with a like and dislike button. As long as we do not abuse such things.

More proof is the tag insults people did, such as lolumad.
