Those are actually pretty high quality references and cover a lot of what shills will do.
From a legal standpoint, the shills are liable according to the following laws:
1) Libel, slander, defamation (they often hurl abuse at targets that are untrue)
2) Harassment, stalking (they often follow their targets for days on end, or try to harass them off a service or area)
3) If law enforcement shill, their activities can overlap with frame-up, entrapment or setups (all illegal)
4) If the shills are foreign agents and they are gathering data on citizens, this counts as espionage (especially if the data they 'accidentally' acquire or read happens to be classified materials - guaranteed if they've tried to attack WikiLeaks etc)
5) Fraud, deception - they often misrepresent a phone number, service or situation as being one thing, when it's actually another
6) Incitement to violence (more a UK thing but you get the idea) - shills often try to provoke or encourage people to conduct violent acts or entice people to act violently
7) Pornography laws (depending on state)
8) Child pornography laws (given the posting of child post is often used by shills to take down facebook pages, threads, comments etc)
9) Wasting police time (especially if they try to get people to call the FBI, police, etc with their phone fraud scams), which leads on to…
10) Perverting the course of justice, obstruction of justice and perjury, depending on circumstance, and…
11) Any of the endless left-leaning laws that allow people to be jailed, sued, fined etc for 'discrimination' (isn't it wonderful how hate speech censorship laws can backfire so horribly?)
12) Any legal reprisals for any foreign agent trying to operate in a given country (I do believe spies are exempt from the geneva conventions, especially if they pose as a civilian - which means the shills, if foreign agents, can just 'magically disappear')
13) Impersonation, identity theft or any of the like (especially when they try to impersonate a poster and falsely represent themselves as such)
14) Whichever country's laws they broke whilst residing in that country
15) If the shills work within the US, then it is treason. If they're employed outside of the US by people within the US, then the people within the US can be charged with treason, the ones outside count as foreign agents, so the other elements apply
16) Assuming they're trying to flood a forum with posts or threads without permission, you could stretch in some computer abuse laws (an attempt at denial of service)
17) If they are claiming something politically, and they're a political entity, under FEC laws they must disclose their political affiliation (attention Media Matters shills: you are breaking this law right now. Likewise, AIPAC)
18) If they are advertising a service falsely or fraudulent, then they must under FCC rules disclose it as an advert, and of course, it cannot be false or fraudulent
19) I believe, depending on state, there are laws against spam - given shills flood forums with garbage, this would constitute as breaking spam rules
20) Attempting to circumvent anti-bot checks with a bot without permission would constitute also computer abuse, as it violates the access permissions of the owner
21) Depending on state law, failing to disclose who your organisation is (even if not politically affiliated) or what your financial interests are, could violate a number of transparency laws
22) The shills failing to delete any data held on you would violate GDPR (yes, an EU law, but that's for the EU shills to get clobbered with - people outside the EU can apply for injunctions against EU based companies)
23) The shills failing to ask you explicit permission to datamine you prior to them doing so would violate GDPR
24) There's an infinite number of technicalities. I think the FBI classically abuse 'wire fraud', because the internet is over a wire, and the statements are fraudulent.
Good Shill Hunting!
