I dont have time to reply to all the posts in here, the long and short of it is I think its working pretty bloody well.
The sin bin system isn't in place. It was half implemented (hence the 6 members being in there) but after a few days of being without NMC I didn't see the influx of crap that I was expecting, in fact I was nicely suprised. We've certainly got a few new decent members, and its good that they're not pissed off by the time they get to access the full site. For a while we had a lot of spammers (note: not scammers) signing up, but I put some stuff in place and that appears to have calmed down now. Moderating time has gone down, reports have gone down, emails asking 'why cant i post' are non existent, visitor numbers have gone up.
I do think we need a couple more mods to catch any 'edge cases'.
Keiren, you say there is a load of spam, but I can't see it, nor can I see any reports in the report center from you
If you do see spam, report it and it won't be long before it gets removed
