Glad to know you're informed about how to pursue this without undermining your case. I just had an image of you posting contact info of this guys associates here and randoms (vigilantes & socks) from the forum spam calling them which wouldn't necessarily further your cause. I was advised to be careful what I disclosed if there will be a potential court case so that's the approach I'm taking, but if you're under counsel then cool.
I hope this guy is reading this forum because it's obvious one way or another he's not getting away with it.
Wouldn't hurt my case - might annoy the hell out of him though.
