I am DMs dream, but I would be on your list as a "bad bet." Why? Because I got on the wrong side of a DM when she did something completely unethical unrelated to her dressmaking and I called her on it. The backlash from her was unbelievable. She'd put me on your list in a nanosecond out of spite.
I know of two other parents who she'd put on there, too, because they challenged her about serious quality issues on her dresses. She has since gone out of business because the word about her shoddy workmanship got out.
So....is it fair that I'd be blackballed, along with others? I don't think so.
