It would be easier for me to visit that section and start reporting obvious garbage posts, don't wait for them. I will improve myself in the process of moderating, anybody claiming to know what is the best method of dealing with garbage posts and tries to stick to it, refuses to improve it. is a lier.
I wouldn't give you to paint my walls in white.
I would pick one of:
Fish guy, because he has impressive amount of non-bad reports.
Loyce, because he is very active in reporting plagiarism and probably other things.
Vod, he has tagged many users for spamming and c/p, probably would be better to allow him to remove such posts?
Others, i don't know, Foxpup is not very active, otkrid70 was hacked, rickbig41 is global mod, shittara007 is yobit spammer - hit'n'run 20 posts in 1.5 hour and repeat every day, and as for me I don't even know how I end up on that list, I don't even read politics neither I remember reporting anything there.
To be honest last 11 reporters have less reported posts together than it is number in "top 20 reporters".
