I have two things to add.
A. Are the people going "off topic" really the obsessed ones?

Since we are in fact talking about different things and not just beating our meat to the current nothingburgers of the case and general WW content. Food for thought.
And.....
B. I really don't think Vic will get the speds to shut up even if he comes out 100% victorious. There are people not directly involved who will never shut up and aren't worth taking to court because they have nothing to their name besides autism and three different strains of candida in their folds.
I'm not sure what would be the best way to handle these people because they have nothing to lose. The only way they'd stop is if nobody cared to listen, but people who want to keep reigniting the virtue signal fire will feed them.
If they aren't getting direct attention from outside sources they might finally stop, but people like that will actively try to cause trouble. Again, nothing to lose. They just want to be right no matter the cost.
