Defamation?
Just sue "Trunk Archive" for defamation/slander/etc.
Request $100m. Agree to take a lower figure in exchange for a cease and desist agreement. Then if they contact anyone else they'll be in contempt of court.... jail time.
If they refuse the deal they'll lose the case.... they can't say "we know it's defamatory but we reserve the right to do it again". Blaming their software isn't a defence.
