Off the top of my head:

-Sold a bunch of merch that was comically oversized and left everyone stuck with unusable product.
-Tried to arrange a deal under the table on an auction gun he got a look at before it went up.
-Doesn't help his teammates reset stages when at a shooting competition.
-Failed to stand up for Karl when ARFCOM was making up lies about him.
-Failed to give IRTV credit for organizing a 2GAC match, when that's basically the only request they make for media.
-Took on Lucas Botkin as a sponsor.
-Copy-pasted brutality rules for his own spin-off match after falling out with Karl, and doing such a poor job he left in references to the venue or IRTV (I can't remember which).
-When asked why he was selling merch with a picture of himself that he hated, shrugged and said "money."
-Treats his wife more like "the help."
-Generally just thinks he's better than you and you don't deserve his respect.
-Abuses copyright takedown requests.
-Removes comments critical of him on his YouTube channel but claims doing so for other people was not possible (Karl, when ARFCOM happened).
-Has expressed deep distain for his own audience.

There's more but that's all I can remember right now.

Edit: I should say that he's generally pretty good at keeping this stuff out of the public eye, these are mostly only things you hear if you know the right people.
