Everyone takes reviews with a grain of salt. Both good and bad. I’m glad people post negative reviews, I would like to know these things before hiring, it’s why I come here. I don’t know what you mean by “rejecting” a client and on what basis you made that decision, but unless you’re sure who the poster is, I wouldn’t presume that’s the case unless you just reject a lot of clients (which is ok , but a little weird). Best thing for you to do is just keep providing good service and ask for reviews. Fake stuff always comes out in the wash. Good service always shines through the bs. But yeah, the PNP label doesn’t exactly support your case, neither does the moral outrage. Ask the poster to remove it. If he declines, say thank you for considering it, and move on.
