Youtube Like/Dislike bugg

Hello People,
I ve a problem. Since a few days when i exchange likes with youlikehits, addmefasts etc i get like normally likes but about the 2 likes i also get 1 dislike.
So i get 50 likes and 25 dislikes, and when i remove the link of addmefasts the dislikes stop. So it has to been addmefasts/youlikehits that does weird of a Youtube bugg.
Have anyone else it?

thats weird indeed.. i doubt it to be from AMF itself.. probably someone running a macro for the likes is doing dislikes as well on same videos..

Its really weird, someone had it too.

Yeah, this has been going on a long time. Probably just trolls on addmefast. It happens a lot more when the points are set to 10.
