It's one step forward...one step back. Our little friend Mi7chy got suspended twice, because the mods finally woke up from their comas. He's been rather subdued lately, and I assume was warned one more strike and he's banned, and thusly has decided to take his marbles and go kick anthills elsewhere. It probably helps that maflynn retired and is no longer able to actively protect the more obvious PC trolls, although he is still posting, for whatever reason. I guess he still has some extra time while not enjoying his Windows PC. Still, some of the less overt malcontents are still doing their thing, and getting new posters banned because they don't know the game over there.
In regards to the non-tech forums at MR, I never visit those, so I can't say much about them, other than I don't know why a site that is specifically meant for Apple enthusiasts even bothers having them if they're just going to turn it into a virtual police state.
