What was the confirmation?
There isn't one, I've done no transactions, but Sublime being the cocksucker that he is has left me bad feedback, don't worry karma will get him back through the powers of his eBay account. He left me negative feedback on here even though he's never dealt with me, so I will do the same for him but on eBay instead.
Anyway I had his 'friend' contact me pretending to be interested, he demanded me to send Bitcoins first, he must think I was born yesterday, his username is: Biglab.
Was the negative feedback given before or after you sent him that PM? Looks like it was before.
If it was before, that was a pretty sucky thing to do as there was no proof but I have to say you've kinda shown your true colours with how you've behaved since then.
Two wrongs and all.
