Shill spotting is a big topic. In regards to the common shill slime that they send here. Some indicators are a strict adherence to the narrative or provided script. Insofar as they won't ever meet you even on neutral ground.

Fed Quixote when he first emerged from his basement, informed us to the effect....he was here to fix this place and correct our viewpoints. Correct The Record perhaps? He's a hopeless contrarian, but I enjoy observing his methodology.

There are many subjects that a normal person would at least concede are possible or debatable that defy mainstream narrative. Not these guys though, line item mainstream scripted rebuttals, until they run out of them. Also DNC type shills frequently weave an anti Trump sentiment into their posts, needlessly even. You will notice they also seem to have a lot of time on their hands to write bloated walls of text to create conversational "noise". It's an "I am very smart" moment and they don't actually say anything that moves the conversation forward.

Oh, and these type of shills seem to be instilled with a great deal of hatred considering their frequent use of slurs, slanders and ad hominem attacks. It's almost like being a maladjusted foul mouthed person is a hiring requirement. They're trained to use propagandized slanders like: extremist, wing nuts, conspiratards, racist, tin foil hat, supremacist....etc you understand.

More insidious type shills are ones that appear to hold similar beliefs as the predominate sentiment of other users. However, they will weave a dissenting narrative that is almost subconscious until you see it.

For instance not too long ago, a user was appearing to be very right wing, until it was noticed that every third post he was injecting the statement that the "right was eating itself". Which of course is a falsehood. It's a common demoralization tactic.

There are others who also appear to be ideologically aligned but they are vitriolic and pointlessly extreme in their positions. Which could include calls to violence. It would appear that they are attempting to create a false association of legitimately concerned people with a dangerous belligerence in a partial effort to scare off people who are seeking answers.

There are so many flavors of shills, it's fun to taste them all!

It's all about perception management, consensus and sentiment influence as the goal.

There are outliers, some people just naturally do some of these things instead of pursuing professional help or a productive hobby instead.
