crazy troll?

I just got mail from this crazy person on curezone, where he accuse me of something, but do not leave and references at all. Does anyone know who this is here?

My firm has been supplying the Sputnik for some 13 years. You have stated in your uninformed post that we supply used devices. This is clearly libellous and damaging. Get down that post or you'll hear from my NY lawyer, John Speares. Ronnie Turner

his name here is rturner I think.
