Dear R0n1n,
Please do share your experience with this guy. If not on a new thread, then on this thread.
It looks like there was another complaint about him (same cell number, different nickname).
I've sent a 'Report Post' to the moderators. Though I think he will reappear with another nickname, I think it should be our responsibility to start the ball rolling.
I looked at both the accounts canon5d79 and HSMSigma, it seems that they have very identical items on sale. I wonder if we dig a little deeper, how many more clone accounts we can unearth.
