I read it as “LW is female and tried to undercut her sister’s (and others’) sex work by trying to scoop their clients and have sex with them for free, after shaming her stepsister for doing it for money,” but it’s even MORE gross if the LW is a straight man looking to have sex with sugar babies without paying.

I can understand KINDLY warning a younger friend/relative that they have too much easily-searchable identifying info on a sex work profile that you stumbled across (i.e., using their legal name in a way that future employers could find), but shaming them is totally unacceptable.
