Removal of moderation privileges from inactive moderators.

Besides him, no one else will definitely do it.

He doesn't even do it himself ;)
I've already given a report on the fifth one. Once again:
SteN -- last appeared in April.
LotR -- July
_Prizrak_ -- September, which isn't critical, but still September
Mish-gan -- relatively recently, but he has a section like that, there's nothing to moderate there, and he got the rights for his mapmaking contest, which ended ages ago.
Primus -- вообще April 2011
Well, Leopolus appeared recently, so that's fine.
WisTrit -- doesn't really moderate, but he has an undeniable plus: he visits the forum and can be contacted if necessary.
That's the situation in general. I said about Lux, the rest are relatively active.
