If your paraphrasing her post is correct then she is warning “bad” clients not to be annoying her but the warning section is for clients to be warned of scams or dangers and as E-I does not cater to serve the interests of “bad” clients I am assuming the reference to “client” in the warning section sub heading refers to “good and genuine” clients only so on that basis and assuming your paraphrasing is correct then her post still does not belong in warning section.
Also it would not be fair to assume she was making a threat to anyone at this juncture. She said herself it was advice to Escorts so if that is so then it belongs either in gen chat or private forum…
