Do you have first hand experience with the mistress that you are so concerned about or are you basing this on videos you've watched? Posters have asked questions and requested you be more specific. It would be nice if you could respond to these posts with detailed information.
As for doms calling others out who they feel are unsafe, it happens. Some times, it turns out to be unmerited. Other times, it turns out to be credible. We've all seen subs with sour grapes go after a mistress and, sadly, mistresses go after subs in the same petty way. As much information as possible should be put out with clear concerns.
Your being so subjective makes it difficult to respond in a meaningful way.
