A few libel lawsuits ought to do, no?

I think it has to be an intentional lie and intended to harm, in the US at least (but don’t trust me on that!). If nothing else it would be interesting to see how it goes!

Other countries have stricter libel laws and willful disregard of the truth is often enough for it to be libel.

as a general rule I think, given the stronger requirements about defamation (because of freedom of speech), that this is not the way to go.
