I think it is a deliberate attack.
It would be a pity to let all the great work by Hort and others be nullified by a troll.
I was thinking of a direct appeal to Mark Carey to ban MT and / or put his posts on "Beyond the Mainstream"
I also think it is urgent that bOnafide should do the archiving of the posts asap.
I've been trying to keep the active Curiosity, Marathon valley and Active Mars threads near the top of the posts but it is not easy to outpost MT and the plethora of wacky posts will eventually make most serious posters and lurkers stay away from MRB.
I think MRB is worth saving. It would also help if some more of the old regulars would consider posting fairly frequently again.
