(I dind't sign it, kek) But i presume most of his content will be old stuff for now, but can be old stuff from his chat group that never got leaked. It's hard to say "if had something new people will post already", cuz a lot of members don't want to share it because somewhat a respect for him or the reason being he was on the old forum.
Sadge, apparently he is just a dude that have a hobby that people are willing to pay to see. MF would make more money than a doctor make in a year in questions of weeks, in the other side is very respectable the fact he is not cashing in scamming on his paid content and just being an extension of his hobby in social media.
