Sheldon nuthouse is bluffing. I’m sure fineslime investigated the accusation as soon as she received the letter. If there was anything to Prof Fraud’s charges they would have produced her long ago.
Now all they have is a close holed letter with unsubstantiated charges to use as a last ditch delaying tactic. Good luck with that in a serious hearing.
Sedition is overt conduct, such as speech and organization, that tends toward insurrection against the established order. Sedition often includes subversion of a constitution and incitement of discontent towards, or resistance against lawful authority. Sedition may include any commotion, though not aimed at direct and open violence against the laws. Seditious words in writing are seditious libel. A seditionist is one who engages in or promotes the interest of sedition.More at Wikipedia
