Moderation statistics can also tell us some interesting things.

Or maybe not. Zero moderation activity doesn't necessarily mean that the moderator doesn't visit the portal and is completely unnecessary.

If you go through the Heroes 5 section, you can find people who haven't visited the forum in a very long time. And since there are no problems in the section, the need for these people as moderators (of the Heroes 5 section, we're not talking about other sections right now) is questionable. For example:
http://forum.heroesworld.ru/member.php?u=5964
http://forum.heroesworld.ru/member.php?u=9586
http://forum.heroesworld.ru/member.php?u=2708

So, what should we do with them? They also seem to be active in other sections. And there, they might be needed. We need clearer rules regarding such things. Although Sten hasn't logged in for a very long time, I think he should be removed.
