What I do- and you can ask Kero and farcast this as they reply to pms lol- is pm anything malicious to them right away either Kero on msn or pm and I pm farcast. It's usually gone within 10 minutes.
Just PM or MSN a global or a sectional of that section. Having mods be encouraged more to regularly check their PMs might be good, but it's hard to answer or even check all PMs efficiently.
