I think you're right - she used to be Kate Chou. Still don't have any intel on her under either name.

on the subject of rebrands of asian escorts, phoebe chen has been showing up in my twitter feed and looks like she is part of the stassi jolie mafia. the photos look great, i looked her up a while ago and found that she had rebranded from her prior name zoe choo. i dont want to give away exactly how i figured this out in case they find this thread, but youll find it if you look at phoebe's web presence closely enough. the reason i want to call it out here is because in my research, her old twitter @mszoechoo was still active and she was complaining about a customer who left a bad review. i dont recall any doxxing but it was unpleasant thread and lots of piling on by the mafia. i went to search for it to post here, but the twitter handle is deleted and the comment thread gone from search. unfortunately cant find it in archives, wish i had taken a screenshot. zoe's photos were different from phoebe too, not as skinny model like, so i suspect that phoebe's photos are fake. you can still see zoe's slixa ad as of my posting date, she probably paid for a few months. i couldnt find the ter review because she had already delisted by the time i started my research.
