There have been instances where a dev was banned even when he had nothing to do with the patch and relationship setters no longer fly either (it's why some AVNs have started with them and then removed that option in later updates, bait and switch at it's finest). They even stalk devs all over the internet to enforce that and devs agree to that bullshit stalking when they put it on Patreon. Besides all that really no one should give money to any platfrom to anyone that's on them that does that shit if they care about privacy and censorship at all. Agreeing to that dumb shit just emboldens them and financially supports it. I've said it before but I'd rather fund terrorism if I have to pick one.
As far as being jailed it depends on location, it's why he left France/Europe. A number of countries still don't care one bit about loli games or AVNs since there is no real victim. Some California judges have specifically stated exactly that during a few proceedings that have refused to indict (so essentially they were arrested and released either immediately after the paperwork or during the first court appearance a few days to a week or 2 later). In the US only a few select targets have been arrested that plea bargained due to not being able to lawyer up, which they shouldn't have agreed to and took it to trial. The cases would probably have been dropped after the bluff was called since obscenity is nearly impossible to successfully prosecute (WTF does "having no artistic value" even mean?), other than Mr. Double and his site but that is an extreme example that demonstrably got real kids raped and killed (and even that was fine for nearly 20 years, so if one is already old make whatever illustrated literature you want no matter where you are, odds are you will die of natural causes before getting arrested if precautions like logless VPNs are used).

Believe it or not he's still alive after 5 years in. Most likely in an SNY unit with like-minded people and has been trading stories most of that time, if he's simply not kept in protective custody/solitary confinement/the hole for his own protection. The idea that every creep and p3do that ends up arrested also ends up murdered soon after is a myth mixed with bit of mass wishful thinking, at least in US federal prisons. Sure, some like Jeff Epstein do, but most have security that makes that exceedingly difficult, esp if sent to a supermax like ADX Florence when they are kept in their own 7x12 cell 24/7 (where that is probably the safest/coziest place in the world for them).
