Charles: sure seems to me that this was something that we all started asking about way back before the current version of the C9 web site. just seems like this has been a topic on more than a few occasions and then dies down for a while... then repeat again.
just pointing out that it has to be kept as a priority and dealt with. no more letting it slide back off the radar till "later".
I for one would have no issues with using a ban hammer if i had one, i would be willing to back up my use with good reasons for any ban/ thread close etc...
I think if we could just mark the post so the post is "hidden" and the same with the account then you or other msft staff could "undo" other folks bans if they were felt to be wrong for any reason.
also like the markers that show a msft staff you could allow use of mod rights to post with "Community Moderator" flagged. as a way to let other know that when this person says "hey cool it off" that it has some meaning... not just some random noise.
if you had say 20-30 niners whacking spam i bet the spammers would learn that the junk would be gone almost as fast as they could post it.
esp. as we have folks from so many time zones.
