I've already spoken my piece on this issue many moons ago.
FYI: I've seen the evidence of cheating back then. Some of it was deemed not actionable even though it should have been. If tech/nations got deleted, there was slam dunk evidence and anyone who still thinks that anyone got a raw deal makes me chuckle. If anything, as I say, the mods and admin erred on the side leniency.
Anyone left here now and is still active has decided to accept what went on, that the punishment was what it was, and that a proper fix for Bob would have involved doing things that Admin was unprepared to do. I'm not sure what else to say at this point. Ya'll (what's left of you) still seem to be having fun most of the time, or maybe old habits die hard and good friends (and frenemies) are hard to find.
