While I can appreciate anonymity, sharing info about "avoid at all costs" in DMs means nobody else benefits from that info. Hearing "someone told me to stay away" is 2nd hand info at best (slanderous at worst), and tells me nothing about if the issues are within or not within what I'm looking for. 🤷♂️
Some people prefer to remain anonymous when they choose not to recommend someone because they're concerned about potential negative consequences or retaliation (so maybe you don't appreciate anonymity enough.) Ilanus, Dundas, and TrideandTide all have good reputations (I certainly respect their opinions), and they're all saying they got the intel from a reliable source. Not only that, a fourth person (Gocanucks1) has
confirmed that information via other PMs from other people. Based on that, it's up to you to decide whether you trust them. However, accusing four different people, who don't appear to be connected, of deliberately spreading false information seems a little too aggressive and, if you ask me, borderline disrespectful.
You don't trust them? Go see her. It's really that simple.
