LAP, his name is still visible in the OP.
I'm with DH on this. A fake review is small shit. Sure it could possibly have some minor effect on your business, but the overwhelming truth is that you probably never would have noticed, if you weren't a member of this board.
Outing a hobbyist is a BIG FUCKING DEAL and a completely disproportionate response. Like running a guy over because he called you a tease. And to have done so in error is way, way, way out of line and inexcusable. You'll get no sympathy here and not likely elsewhere either. You're officially off my list.
