Is it possible to copy or print entries but redact the information that would be sensitive or personal on the copies? Either with a Sharpie or correction tape?

I've had something similar happen to me, someone lied about something I had done and I had proof. Fortunately I didn't have to redact any information in that setting, but if I had ever needed to take it further I would have had to.

I feel for you as it is difficult to prove things like this and you feel totally helpless.
