Actually, I reported him at AAC, and Bertus responded by PM. AAC was aware of the problem with his just previous incarnation (watsongrey) and have diminished his activity significantly without invoking a ban, which tells him he needs to re-register. It sounded kind of devious and clever to me, and I will keep an open mind and see what works best. My bias is toward banning and blacklisting, which AAC. EP, ETO, and EDABoard could actually collaborate on.
