Here's one highly suspicous exchanger site - www.ukash-pay.com
Why suspicious? Well, first it has no SSL and you're as an user supposed to enter some pretty sensitive data.
Then, it looks like made by 15-years old, and finally
it has two fake banners in the bottom, one is "Verisign" and another one is "McAfee Secure". Considering all of that, I'd advise everyone against using this site. The possibility of scam and fraud is just too big, considering all of the above mentioned.
