[Admins]

Ok the algortihm was bugged, it was not detecting inactive members at all.
The inactivity check has been fixed. I have also updated the rating algorithm to make it actually possible for big guilds to have a positive rating. Inactive members are still decreasing the rating of a guild quite a lot though.

The new algorithm for rating is:
inactivity < 3 days: +4 rating
inactivity < 7 days: +2 rating
inactivity < 30 days: +1 rating
inactivity < 60 days: +0 rating
inactivity < 120 days: -1 rating
inactivity < 180 days: -2 rating
inactivity >= 180 days: -4 rating
