That's true. We've already seen how quickly they mobilise when a fedpost is spotted in the wild.
Another option is to keep the threads locked, with the KF militia being spotters rather than jannies. By that I mean they'd be the only people able to post in a locked thread (like a janny), and it'd be the spotters' responsibility to post new information to the thread. Strictly observe and report,as per the Farms' longstanding ethos.
Unfortunately there are too many people on here who - either through naive autism or acting in bad faith - can't/won't just observe and report. Observations and reports are important; plugging the neghole to prevent pozloading moreso.
