I'll take a stab at summarizing.
1. Mean/Bully - As mentioned above, he often uses (used? if you believe his claim he has turned over a new leaf) personal attacks against pinsiders or people in the industry. He has a hard time going three episodes without attacking Hilton.
2. He is a bad Drunk. His drunk podcasts only further prove that beneath it is all he is mean spirited. Furthermore, he drunkenly disrupted the women's New York Pinball Championships in 2018. That cemented the tournament players mostly hating him. At that time, he threw a drink at Tim Sexton, cementing his blacklisting from Stern.
3. He is a Narcissist (IMO) . Anyone who starts an avengers discussion livesteam in a skin tight spiderman outfit flexing for the camera to a bunch of other geeks, must be a Narcissist. He also couldn't stand not being heard when he was "out" of podcasting. He quickly took up facebook live-streaming.
All that said, he makes a very entertaining podcast and you should decide for yourself.
