Years ago, a model I regularly visited had a guy that would come into her room and write of suicidal thoughts.
Obviously in addition to emptying out the room of many viewers, it was difficult for her to try and deal with him anytime, but especially mid-show; she asked me if I would talk to him via pm. Against my better judgement, I agreed, because I could see how it was adding stress to her while trying to work.
Anyway, that was a terrible move for me - I won't go into the details, but every single time I joined the room, this guy would start up a pm conversation and pour out all his troubles. His negativity ended up making a visit to that room a PITA whereas before it had been a place of total light-hearted fun and entertainment. In the misguided belief that I was preventing this guy from negatively impacting the model's work, I kept up an attempt to help him for several weeks, until one day it became clear to me that my own mood was very affected, and I was finding going online more like an obligation than enjoyment.
Made the decision right then to tell him firmly that he must seek professional help.
