There seems to be at least one of each in a lot of forums and comment sections. I see them in a lot of places I look.
Their MO is the same that we can observe here in the Bilge: show up in any thread that might be critical of their masters. Their posts are aggressive, ranting diversions, full of whatabouts and rabbit holes. Every Western news source lies, but they have insider knowledge and are the only ones telling the truth.
In online discussions of a higher order, where logic is required, they end up isolated and discredited, but this rarely discourages them.
