I’m not a fan of public shaming, even if you think someone is a scammer. As many have said here, different people have different experiences. If someone wants details about someone I have hired and they’re open to DMs, I am happy to provide details of my experience, including my belief that the person may be a scammer. I just don’t feel comfortable poisoning the waters for someone, based solely on my own unpleasant experience. I also wouldn’t want providers to do that to me as a client.
