So we come back full-circle. Jared has diminished freedom of speech/dick sharing privileges than the rest of us, because his face is more recognisable.
Also, assuming the best, that he wasn't indeed targeting/intentionally welcoming kids into his porn blog (I think it's fair to give him the benefit of the doubt here, given the lack of any substantial/reliable testimony against him, and the active banning going on), why should he be expected to go any further?
When parents let their loose on the internet and the government provides absolutely no support to adults trying to keep kids out, why is it that we're dumping the responsibility for age-gating onto blog/site owners? I think they should be expected to do everything in their power (within reason), to keep kids out, but when that doesn't suffice, they should be absolved of responsibility (and I believe they are legally speaking, but I'm not a lawyer). At some point you need to say "ok dude, you've done all you can barring limiting your own rights to freedom of expression, good job, maybe we ought to demand the government come up with some technological solution, and shift blame to parents".
The internet is a wasteland and handing out unlimited access to it, is like strapping a pip-boy to your kid's wrist and telling him to go out and do whatever he wants.
Just because Jared is a quasi-celebrity and porn is for some arbitrary reason, socially unacceptable, doesn't mean he should be held responsible. I agree with you that running a porn blog as someone who profits from popularity is stupid and bad for business, as a lot of people want to act as though the world is populated by virgins and kids are flown in by Stork Express, but that doesn't mean that what he did is ethically wrong.
As for the membership - I really don't care if the community was made up of fans or strangers, so long as he wasn't bartering special privileges for sex/nudes. No one would bat an eyelid if someone said "I joined his Twitch community because we slept together and I love his monster dong". Transitioning from fling to fan, is equivalent to transitioning from fan to fling, at least in my view and where consenting adults are concerned. If a person has an issue where they develop celebrity crushes and can't stop themselves wanting to get as close as possible to some celebrity they've never met...that sounds to be like some sort of psychological addiction (disclaimer: not a psychologist), and maybe something to take up with a therapist. We should all be mindful of people with psychological issues and be as respectful and supportive as we can. We should certainly not purposefully take advantage of someone with issues (i.e. gambling addict, sex addict, etc), but we are also not responsible for their destructive behaviour.
