Yes, but no one's going to do anything about it. Back when there was that shitstorm of that little girl with the hardcore furry parents who brought her and her cheap homemade fursuit to a convention (where she was teased and it blew up on Twitter) there were a handful of furs who reported her account for being way underage, and all Twitter did was kick back a canned response about how they'll only take action if the person reporting the account is a direct family member or some bullshit.
I feel like Violent J ought to know at least a little bit about the fandom now that he's made that silly video, and if he's still okay with his 12 year old daughter engaging with a sea of weirdos on furry Twitter then that's his prerogative. The man paints his face like a fucking clown and raps, I wouldn't expect him to exactly be a paragon of good judgment.
