The 'watchtower' group on facebook is just an apostate group from the internet with thin sheep costumes on. They know most witnesses will not browse the internet for witness sites knowing most are apostate, but that we have become comfortable enough with facebook to let our guard down. Most can be identified by their list of apostate friends or pages, but others blend in. This is why we need to get off of facebook sites and not befriend anyone we don't personally know. Their main goal is to make you doubt the faithful slave class.
