I get what you're saying but I think you know quite well that with all the current tools in place - Patrol page, reporting to mods, Meta, etc - there are still shithole sections of this forum where anything goes. Altcoin threads for example. I can't see how adding one more thing to patrol is going to help.
Two more things quickly come to mind, ponzi scams being pushed into the IBG section instead of being outright deleted (yes I know, that is forum moderation policy and I have to accept that),
or the gambling discussion sub (which I partly suggested myself, but I'm not so sure about it's benefits anymore).
I think the moderators of those mentioned sections are doing a good job given what they have face on a day to day basis, so dont misunderstand this as me blaming them directly for the state of certain subs or sub-child.
mprep especially, I imagine has to have quite some patience and nerves to keep the upper hand on all the altcoin stuff going down. I've got mad respect for that.
