Ya, a lot of them are folks that you wouldn't know if you weren't there, or even if you weren't there for longer times than just the conference (I generally stayed in Aca for 1-3 months each year)

as far as i know he has prev denied those allegations of fraud and theft etc

That's been the normal response, and as people dig up more and more or provide evidence of his connection & knowledge, if not intent & responsibility, the issues are quickly ignored and the folks researching are generally threatened and quieted as much as possible (I saw this personally when he was on STEEM in the early days, and there were folks here calling him out.)

i also haven't heard about any sex harassment allegations prev

Ya, unfortunately none of the women ever really go "public." Everyone who lives in Acapulco, has been part of the conference team, etc. knows about it, but his money + influence seems to keep everyone looking the other way.

also surprising given that he is a family man isn't he? or maybe that took place before he was married?

It's still happening, most recently I know of was at Anarchadelphia back in September, and I have heard at least an account or two a year since I first went to Anarchapulco in 2015.
