What happened:: bitblender scam site, the link was clicked direct off darknetmarkets.org
Reference Link: http://bitblendnlwdwxiy.onionAmount Scammed: 0.00105
Payment Method: Bitcoins
Additional Notes: Deposited money on the quickmix section, deposit never registered on the website. Poof! money gone.
You were indeed scammed by a phishing site that was posing as the real bitblender, it seems.
I've never heard of any major issues with the Bitblender when it comes to mixing coins and certainly they wouldn't risk their reputation for such trivial amounts.
If you were provided that link from the site included in OP, then I wouldn't be surprised if that site was owned by the same person that operates these phishing mixers. When you are using any mixer, whether via TOR or on normal browsers, make sure that you are connecting to the right web address. And don't trust third parties, only trust posts on the ANN threads themselves.
