Lol...He's never said anything to you about it? Check em out sometime, Michele. You'll see why he's never said anything to you...lmao.
(It is possible, though, that he simply hasn't paid attention to them, too. So, I can't say that he's deliberately keeping anything from you) . It really isn't THAT bad so long as one understands the intentions of the behavior behind what trolls do....they deliberately slander (and sometimes quite offensively) TO get a reaction.

My daughter has account on there, too. She makes many of her own vids (using that Sony Video Edit program thingie...lol), and from her online game, Toontown. She has a few thousand subscribers...O.O.....apparently, that's the craze amongst her and her friends.
She's on Youtube...ALOT, and has sent me links to tons of various vids, (mostly funny ones). Upon reviewing some, I've commented to her how vile some of the responses by these trolls can be.
She's told me that those trolls are commonplace and to just ignore them.
So, I do....
