New term:
Carpetbag Troll (noun)
A carpetbag troll is someone who doesn't live anywhere near the local communities that Waccobb serves but creates an account solely for the purpose of proselytizing intensely about a specific cause, theory, or cult they are hyper passionate about. Carpetbag trolls sometimes (but not always) act rudely and denigrate local community participants who don't agree with them, as carpetbag trolls don't have any continuing accountability to that local community since they don't live there.
It has been observed that during a contentious online discussion if one carpetbag troll gets strongly challenged, or gets in over their head and is unable to coherently defend their position, they sometimes call in additional carpetbag troll associates to provide support. In the case where a "bigger gun" expert is called in this is called a "Cyberringer". A group of carpetbag trolls will often coordinate their efforts and try to overwhelm a discussion thread with their often bizarre narrative. It sometimes takes several weeks to realize that a discussion thread has been infected by a cabal of associate carpetbag trolls. Used as in, "I notice about a week ago three carpetbag trolls joined Waccobb and are now taking up most of the oxygen and diverting the discussion to be all about their way out there conspiracy theory."
