Why?

The purpose of the activity check is to make sure that official clans are active. If 6 people playing ingame qualifies a clan to be active what sense does it make that another larger and older clan who has 6 ingame active people fails that same test?

They are both producing the same amount of activity. Purely because the new system doesn't take into account inactive ranks, one clan now fails while the other passes. How is that more reasonable than my suggestion, which brings back a safeguard we had in the manual checks?

ALTERNATIVELY... You could always relent to the masses and award more points for forum activity. This ham-handed attempt at forcing clans ingame is really pissing people off.
