Excellent choice of the moderators- well done guys.
Stands to reason with only 4 proactively watching the new accounts and troll etc that some will slip by. No doubt the moderators will have tools to help them identify these issues more effectively.
You don't know who's a troll ultill they start posting. Those 'trolling' posts were getting reported, and only admin had the power to review the post reports and ban if necessary. The mods now have this power, so that's a good deal of work of admins shoulders.
New accounts need to be reviewed for returners and multiple accounts. Hence the ability of the mods to see the IP address details.
Good luck mods, and I hope admin has seen a reduction in his well appreciated workload
