Post all his info on the Bitcoin Shitlist
I'll deal with him if he wants it removed
Just refrain from posting his dad's info, but post all his other online ID's.
I don't think going that route is the way to go. Connecting ourselves with a site with nothing more than slander will not make us look good. We have other real and effective options if we want to use them.
There is a real company behind that website, with a legal team. Don't let the whois privacy fool you. And if you look closely you'll see which company it is. You are just buthurt because someone posted that you are a fussy prick, which you are indeed. Sue us if you think we are slandering you. Our lawyers will be thankful...
Since that post was made, and you proudly showed it in your sig(I have screenshots with timestaps proving it), not even once you tried to refute what was written there, so I must assume it's the truth...
Also, I have an edit on that post striking wahtever was out of line there. Fight that if you wish. I'll PM you all my company info if you wish to prosecute us.
