Oh yeah, they do. And steadily, since it's gone corporate (taken over by Google) things have gotten worse. Whoever is running stuff is getting heat over the Charlottesville videos that don't agree with the Corporate narrative. Quality videos, I mean. Some of the speculative non convincing stuff seems to stay. I'm not the first to have my video removed - other people who did short critique's that were skeptical of certain things have had theirs removed for very reaching and generalized "violations" People who have 10's of thousands of subscribers. My channel apparently was allowed to go for a while (seeing as I had 0 subs when I posted the Charlottesville video) and had several thousand views in just a few days and 38 new subs in the last 2 weeks or so. Within about a week though - I had an "age restriction" on it.
I've appealed the decision to have it removed but am not holding my breath. They didn't even pinpoint where in the video I am supposed to have violated their rules. I'm supposed to have got an email - but I have not gotten it. I've witnessed footage of clear and very damning instances where the directors of the "car scene" are drawing the attention of just about everyone there that apparently keeps getting removed from youtube (it's on other video hosting sites though - ones that right now I hope get more and more attention).
