Nope. I get the exact same thing (to the point where I no longer search for things on YouTube, the thumbnails can be pretty disturbing). I've audited my history to check for that sort of thing.

I think YouTube has just put me in a gender/age/location bucket and figures other people in the same bucket like that thing.

(But actually, who the fuck is watching this shit.)

Edit: plus if this was history pollution then this gross shit would show up on the home page or else where. It is exclusively in the "you might also like" shit that youtube hides in the search results.
