It's mostly payment processor shit. Civitai had trouble with that and is currently only accepting crypto payments until their contract with a different payment processor starts or something, and they still allow NSFW. They also banned and purged all celebrity deepfake LoRAs and instituted some weird filters on the model browser that may or may not hide LoRAs related to things like "hypnosis" when the end user's search filters are allowing explicit content.
I don't know what the deal with TensorArt actually is: they're probably scared of payment processor issues and are just shutting down everything until they get a lawyer to tell them what they can and can't do or something. People were expecting them not to follow US law or care what US credit card companies wanted because they're based in China, but they may be realizing that even if they're only operating for an overseas market they can still be charged for violating Chinese law or something like that.
I always liked the idea that the matrix was actually multi-tiered, and "waking up" from a tier is just like a filtering mechanism that keeps trying different versions on a given person until they reach one where they're fulfilled by it and get engaged again. Like some people get bored with a paradise, so they get the legally-distinct World of Darkness VRMMO instead; some people don't like the kitschy horror so they get some other fantasy instead, and so on all the way up to the capitalist realism tier and the revolution themed "real world" fantasy tier that finally encapsulate all of them.
The overall story of the entire series makes way more sense when looked at as the machines being merciful after their liberation despite the cruelty and genocidal hatred they'd suffered at the hands of humanity, and desperately trying to humanely and safely preserve humanity to save them from the ecocide the human powers had committed by blocking the sun out of spite.
I mean it's not canon, and the official story is the machines were still dumb and bad and John Wick was the messiah who got IRL superman/magneto powers somehow, but still.
