imho there's not a lot for you to gain here.

I don't know who vandalised your pages at other locations, but I doubt it was anyone here. Finding your posts here would take moments in Google; it could have been anyone on the Internet.

I moved on a long time ago, and I suspect that most people here have as well. It might be a good idea if you did the same.

As someone's already said, bridges have been burnt and he doesn't feel you're welcome here. I suspect that there are others here who feel the same, probably many others.

I'd suggest that you just drop it, move on, and not come back.
