Looks to me like we were cruising along quite nicely until mojo jumped in with his stuff trying to create crap.
It's hard for some of us to ignore the BS, myself included, and he/she/it knows it.
I've never been one for booting people out of a place because I would have been gone very long ago.
It is certainly not my place to tell you what to do but maybe banning mojo would solve a major part of the problem.
As slack as this place has become, the few of us that remain do enjoy it. I for one would hate to see this place killed off due to one trouble maker.
I think he/she/it would be accomplishing their goal if you shut the doors.
That's my two cents worth, at least.
