I know everyone thinks these two are sisters. I personally don't think they are. They don't carry on the same type of persona like two sisters should.
That's just my opinion. It could be right or it could be wrong.
The Karma has always been that way. When someone likes what's posted most will give it a -1.
I don't know the reason for it being backwards. I used to watch it all the time now I don't even really think about it anymore.
