Same here.
He was once a trustworthy member of HO Interchange (formerly HO Yard Sale). He recently started posting there again. I contacted the moderator/admin of the group, and linked him to this thread. The admin confronted Josh with the info, and asked him to resolve it. Josh agreed to resolve it, although he never contacted me to do so. So, after waiting a reasonable amount of time and seeing that he did not resolve the problem, the admin removed Josh from the group to prevent anyone else from being victimized. I don't think Josh has any intentions of actually resolving this.
