> No - and in fact in my view this is the core problem with these kinds of situations - there isn't a long established process validating a set of accusations, that if true, fall short of criminality but should result in your exclusion from a community. > Individual communities have to establish ground rules for these sorts of things to protect the vulnerable.

You can never sue anyone for ostracizing you from an open community, or for the consequences of that ostracism. There's no limit on who global communities might choose to ostracize. It's so fundamental to how we group together; you always have to know the norms.

British law is famously friendly to wealthy litigants, and the High Court for awarding ruinous damages. The OP took an opportunity to sue four signatories who (from my understanding of the court order) put their name to harmful allegations that they didn't know the truth of. The four defendants paid £20,000 in costs and damages.

Unfortunately for the OP, the ostracism clearly still stands, and despite going to the High Court to sue for libel, the first-hand reports of his conduct are still online.
