EETree LLC seems to be a shell company owned by EETree Info & Tech Limited in China (https://www.eetree.cn).

I'm not sure what that means as far as payment processing etc, apparently sellers were all cut off with money owing and still have no explanation.

Also the AI-generated blog post on the Tindie site (under the name/account of assumedly-previous staff?), and the post above that says absolutely nothing about what's actually going on...

It looks from the outside like a Chinese tech blog just randomly bought Tindie, broke the site while moving it to their own servers, and now are trying to figure out how to run it?
