I think it's human nature to want to put closure to something so we know we can assign blame or responsibility to someone or something. That said, given that a person 9/10 wants their private life to remain private even if they're famous/semi-famous, expecting a proper, detailed explanation is pretty generous of a creator if she offers one up.
I also suspect that depending on the personal circumstances, staying silent while a situation is playing out ensures that they are safe and given peace of mind that, in the case of a stalker, it's not fodder for them to keep trying to track or stalk them. Aftyn doesn't do herself any favors by keeping her websites/platform accounts running - it suggests she ended up losing interest or getting what she needed and took off with the money once she fulfilled her requirements while she was active. If there was a stalker, she should have gotten smarter and tried wiping as much of her digital footprint that she could control - inclusive of her websites and platform account pages. Therefore, she maintains something a fan club that brings out potential stalkers by allowing her pages to exist - that's on her and she should know better if her problems were due to stalkers. Mai on the other hand probably was a little too naive about sharing her whereabouts at different times and that's a shame - but she doesn't come off as a scammer/flake the way Aftyn does.
This is the seldom-understood risk of a subscription service that is crowdfunded and where it's not run directly by a corporation/middleman: the creator/owner has the freedom (if not included in the Terms of Service on the website or expressly permitted) to charge whatever she wants, to upload/film at the pace and schedule that she wants and she can close up shop/cut back/change up her content whenever she wants - no matter whatever they promised, no matter what was in the previews that didn't make the final cut, no matter what their enthusiasm was towards patrons, no matter their personal circumstances. It's not just porn - crowdfunded anything generally isn't bound by a formal/legally enforceable contract where if someone feels shortchanged or a creator is failing to deliver, that's the risk the buyer/patron takes on. I dare anyone to take a look at indie game consoles that have been toiling for months, sometimes years because of circumstances the manufacturer can't control (supply chain issues, people leaving the project, etc.) - in good faith, those people who donated may get their money back if they ask/demand it, but it's not guaranteed either.
