Don't quote me fully on this, but as far as I remember there was a match in AAA back in 2017 which involved both Courtney Rush/Rosemary as well as Sexy Star in Mexico that ended with Sexy Star winning after putting Rosemary in an armbar, dislocating her shoulder in the process.

There was a lot of discussion and debate whether not it was an accident or a legitimate shoot but people quickly leaned towards a shoot given that this incident as well as the Taya Valkyrie/Sexy Star incident happened way too close to each other. Cody Rhodes and Road Dogg if I remember made comments saying that Sexy Star should be blacklisted from any promotion and on top of that will never be welcome in a locker room they're in and just like that the entire IWC who loved Sexy Star and her work in Lucha Underground up to that point turned on her faster than Vince McMahon turned on Zack Ryder's push in 2012. Sexy Star's reputation as a wrestler was completely damaged then, the blacklisting came into effect (and for good reason I believe, never okay to legitimately harm people in a match on purpose) and she hasn't surfaced in any major promotions ever since.

At least, that's what I remember.
