On the BSV supporters, I'd suggest going through some threads on r/BSV and see how it works out there.
I think in general a small amount of BSV supporters coming into a space with experienced BSV debunkers does little but harm the scam: They show up and have their claims tested against facts, get pressured to justify their positions, and -- in short -- get ripped apart. When they're not too obnoxious they're a lot of fun to debunk, and it keeps the conversation going during the long lulls. Though because of this, it seldom happens even when it's permitted.
The situation is different though when active BSV debunkers don't outnumber them.
One of the really good contributors to rBSV is even a former BSV investor (though he never was one of the clowns out spreading pro-Wright lies-- AFAIK not a single one of those has ever been flipped, they just disappear from the internet if they get convinced that it's not real).
The biggest problem they've created on reddit is that interacting with them gives them more opportunities to file false reports and get accounts suspended.
r/bsv does eventually ban them but only when they're outright disruptive and harassing people or doing stuff that might get the subreddit in trouble, not because they're promoting the scam. The assumption is that >95% of the readers in rbsv are well enough informed that they're already immune to the scam (or soon will be) so the only risk to worry about is that they become annoying instead of fun for the honest participants.
Something absolutely needs to be done. If not a subforum, I'd settle for a sticky at the top of every single forum and subforum containing the text:
Craig Wright is a proven liar, charlatan and identity thief. SV is a worthless scamcoin. Anyone who supports either is scum, bereft of human decency.
Followed by all the documented evidence of Wright's forgeries and lies.
Back in 2017 I circulated a message to people to see if I could get a lot of long time bitcoiners to sign onto a message saying:
Over time his necessity has evolved from a simple (although high value) tax rebate scam to an advanced fee fraud (nigerian prince) to what is,
Was it necessary? Why are you linking his fraudulent activities to the Nigerian community? You know that would irritate anyone from that country.
My apologies. I have the utmost respect for the people of Nigeria-- but few people know what advanced fee fraud is, and the particular brand of spanish-prisoner-con (apologies to spaniards) is known to essentially all english speakers as a nigerian price scam. To this day I receive frequent nigerian prince scam messages though they're finally starting to be outnumbered by tech support and amazon refund scams originating out of India. Every one of us lives with negative things done by some few scammers in our countries. I can only promise you that I know that the actions of a relatively small population of scammers in Nigeria doesn't really reflect negatively on the rest, and I'm confident that most people feel the same way.
Wright's scamming does has an African connection-- but it's by way of a conspirator in Kenya, not Nigeria.
I don't think an entire sub board would be necessary right now. Like others have said, this info would be best confined to their own relevant thread(s) and sub boards are only created if and once there's demand so that's the place you should start. Still, I don't think we need an entire board and could even be counter productive as I'm sure Craig would find a way to turn it into a win or a point of attack. He usually does.
...
Yeah, maybe rename it to BSV/Faketoshi scam sub or something.
LOL I agree on the name. Really I'd even leave BSV out-- without Wright it's just another irrelevant altcoin-- except the two are hopelessly intertwined and often people who need to hear about Wright are looking for info on BSV, since BSV is one of the ways they monetize the scam. Increasingly so as they've now agreed in court that BSV will now be handing over "his" coins.
I don't think crowdsourcing this type of information is probably not the best way to accomplish your stated goal. I think it would probably be better for a group of well-funded individuals (presumably who have been subjected to the kind of harassment described in the OP) to hire an attorney to privately contact those who have lawsuits filed against them with information about how to best defend against these kinds of cases. I have noticed that many of the cases have been filed outside of the US, but in the US, courts can only consider information that has been presented to the court, and the court will not consider publicly available information if it has not otherwise been submitted to the court (also, generally the plaintiff or defendant has standing to submit evidence in most situations).
Nearly all of the quite powerful discrediting used against him in court so far has come from the community. Truth has the property that it's reproducible by others. So when community members find information which disproves Mr. Wright, we're able to point the lawyers at it for validation and reproduction. This is essential because replacing the public's efforts in isolating the conflicts and contradictions with paid experts at hundreds of dollars per hour would be utterly ruinously expensive. Your mental model of "well-funded individuals (presumably who have been subjected to the kind of harassment described in the OP)" is just off base. They do not exist. Wright and his conspirators are legitimately well funded: They expect billions in return. All his opponents can do is hope to mitigate losses (unless they flip and accept his bribes, I've heard that he's offered as much as $10 million dollars to people for supporting his efforts), even where they technically have the means to pay for the litigation it's with a heavy heart because it comes at a great personal cost with no hope of a benefit from it other than Bitcoin's continued health.
The fight in court is also a public information war more than you realize. When some professional-- a lawyer, a press person, a ghost writer, etc-- is contacted by Wright to take Wright on as a client and effectively become a paid conspirator in his scheme they have to decide if they're going to be able to plausibly deny knowing it was fraud to protect their reputation later after it collapses (and potentially avoid criminal charges themselves). The more limited Wright is in his selection the less successful he'll be. What the rules say and what the practice on the ground is are two distinct things: even judges in the US absolutely do look at what's said in public, even informally, and are going to take a second read of things which might end up making them look like idiots in the future. Some of the arguments -- like general impossibility of Wright's efforts to force a coin stealing backdoor onto the network-- are themselves directly a question about the public temperature on the subject of his demands and several times already mass media articles have show up as evidence in court cases as evidence of the public's perception of the subject.
But also the fight in court is also only one element of dealing with this fraud-- it's the most obnoxious because its the one where "just ignore it and let him scam people" is not a realistic option (at least for the targets), but his attack does go beyond court. For example, Wright's conspirators have been meeting with heads of state in many parts of the world pitching their agenda (which involves outlawing bitcoin and adopting their Bitcoin knockoff). The only way they're getting these meetings is that whatever overworked staffer is vetting the schedule does a quick search and doesn't find information that exposes what a big reputation risk an association with this conman and his con would be.
