POBs are usually supplied by one or two people. The whole faction usually doesn't supply it.
The faction activity for most of these groups was bad in the month before that too, I believe.
And if you lacked the members that month... holidays wasn't more than half the month.
Edit: The ID tracker would be perfect and have no downside gameplay wise imo. Some factions could play even better this way.(Intelligence Agencies, Wild, Pirate groups, other people that want to hide, factions no one likes)
