Maybe not many people are use exch.cx, I didn't even heard of this exchange.
probably because it's fairly new, about 10-11 months old and they also haven't bothered to advertise themselves.
But they are ranked highly on kycnot.me, with a score of 9/10
Did anyone from bitcointalk forum used this scam exchange and lost any money?
Apart from the unpaid campaign participants, I doubt if there is any member here who was scammed otherwise we would have seen a number of scam accusation
Total ripoff.
Sadly nobody spent time doing plagiarism checking for them, and I think this must be done when there are campaigns in forum.
We usually have very sharp forum detectives who just need an hour or so to detect such anomalies but i guess they were destructed by other service events at that time
