He has a checkered history on social media.
He posted a 12 year olds user-tag (of a games console) and tried get his fans to harass him, the kid was racist towards Mark Hunt or something. I think he was even threatening to get the police involved.
Some homosexual fan sent Mark Hunt pictures of his backside, Mark then publicly posted them online and wanted people to identify the guy.
He shared a video from a gore site of some dude getting his hand cut off (a video from some shithole country, the guy was a thief).
He has banned many of his fans and been a right wee cheeky cunt on twitter and facebook. He has the personality of a petulant teenage girl.
Basically, he's a bit of a prick. Most grown Men would just ignore the illicit pictures they receive (female fighters receive 1000s of such pictures). They wouldn't get their fans to harass a kid and they wouldn't publicly post brutal videos of violence, condoning the acts.
He's a PR disaster.
