@pb13,

I was replying when you posted, but as you now know I also use a VPN.

My theory about ustrader is that if he was tech savvy enough to use a VPN (and his alterego would coincidently use the same VPN provider) he would have been able to answer my inbox question without any difficulty and continue his enthusiastic posting.

For me, the matching IP isn't the smoking gun, it's his suspicious reaction to a simple question which admits of a simple answer - unless, of course, it doesn't....
