I don't think so. They introduced "Brotherhood Activity" which basically disbands your BH if fewer than 60% of members are active for more than 2 weeks:

A lot of us complained against this and Plarium listened to our remarks like it always does (yes, our complaints fell on deaf ears).

I hope you get a more useful response from a Plarium representative, but I wouldn't count on it.

P.S. If you're wondering about the "rewards" mentioned in the screenshot above, they are useless. There used to be a few hours prestige activator among them, but they removed it after several weeks.

Thank you, gentlemen! 

Meanwhile, I'll close this conversation.
