well, in theory, you could download Google Talk (assuming your account here is linked with a gmail account), leave Google Talk up, and get a notification every time a new thread in the reports section is made. that's probably even more accurate and timely than refreshing the page.
For the most part, people who aren't admins or mods posting in a report thread are shitposting without realizing it. Restating the same thing that someone had said earlier in the thread, contributing not at all, things of this nature.
zal's idea would cut down on those folks but it wouldn't stop them. it would prevent people from having to rename threads and crap so vigilantly, even though that's only been a problem very recently. most people don't get reported with the N word in the title of said report.
(although there are more efficient ways, I'm sure, of preventing the latter)
