I have another one to add to my list.

People who make Troll Accounts on messaging boards.

Seriously, who would care to waste their time making a fake account for whatever reason the choose so they can get a bunch of laughs at the expense of others? I mean, yeah I can see where it can be fun and games, but when people do it to their friends and make it as a way of pulling pranks and doing things they otherwise wouldn't do on their main account or like in real life, then that shows some cowardly behavior. And not only that, that seems to me like it's a big waste of time doing something that could be less hurtful and not as retarded.

I hope that there isn't any shanagans going on like that right now...
