I think there should be a very solid rule about this. My ideas:
No double-posting unless a post is too long to be kept in a single one. If double-posting is found, a moderator should delete the 2nd one and edit the first one by inserting the 2nd into it.
I think repeated bullshit results in a warning of the user.
This way, the mods have more stuff to do and furthermore, the warning system is put to good use.
And on a higher note, do the inactive mods get demoted or does the group of inactive mods grow like bacteria in agar? I can't remember last time I saw Innova, Cybog, jane, Killerbabe, Zekk, joseph (who the hell?), or squirrley post anything, much less moderate. Not trying to be an asshole, but a lot of things are just better when they're organized.
