Want to know why the "rumors" started? Well, first of all, he was banned for sharing Loli/shota porn on the official discord server, the principal MOD from there told me the whole story and there are many other members from that server that confirms the MOD words.
From the moment he was banned he started attacking the itch.io page of Superhuman because he got pissed from being banned permanently from the server, he even begged the mods to unban him but, in the server we are VERY STRICT with the rules, specially if someone shares Loli/shots/cp, that's a direct ticket to a permanent ban.
Secondly, I found out that Josh was playing and supporting a porn lolicon game, here's the proof, a screenshot I made last year when Josh was attacking the Superhuman itch.io game page.
