Your libelous accusation. . .
. . .to definitively repudiate your slander.
Since you're trying to play lawyer, Mr. Community Liason, which one is it? Libel or slander? They're not interchangeable terms.
The fact you are threatening and actually continuing to knowingly push a false accusation until your demands are met demonstrates you aren't making the self-mining charge in good faith.
That sir, is called extortion.
See, if you want to play lawyer, it's important to actually know what you're talking about first. Extortion is trying to get money or property which you're not entitled to from someone by means of threats to their property or family, or by falsely claiming to be entitled to it. This situation in no way resembles extortion.
