From what I can tell some of those accounts imitating the likes of the pharma company, nintendo etc are still up 12+ hours later, because it seems no one at twitter is looking for them
I'm just guessing here but seeing as Twitter has been transformed into an autocracy revolving around Elons balls...
...that if those offending tweets instead presented themselves as Elon Musk confirming he paid off that woman and NDA'd her regarding his sexual indecency then the 2 people doing the moderating would be more motivated to erase any existence of it being posted.
