See what happens when you release unsubstantiated tip lines (intake forms)?
That's life. Just because it's unsubstantiated doesn't mean it should be hidden. Also, if it's so unsubstantiated, then sue them for libel.
We have all faced situations where people have accused us of behaving in a way or doing something we didn't do. When that has happened to me, I don't resort to trying to silence people. I just explain why they are full of sh1t.
