I'll link the videos, but since they're all so long I'll give a TL;DR.

Pyrocynical, GradeAUnderA, and LeafyIsHere have all made videos exposing DramaAlert host Killer Keemstar for being a pedophile, racist, and just all around scummy person. Keemstar responds today with a 50 minute long video saying all those clips were taken out of context.
