Mea Culpa.After reviewing all the information, it is 10000% sure that coboguard who pretend to be a scam hunter is actually a scammer,
behind tether-tumbler, bitwhisk.io, and many others.
He also try to scam people by using a modified chipmixer Tor URL.
I thought chipmixer might be his website as well, as he advertise it in his bitcointalk profile.
But I have to admit, i don't see any real proof that the real chipmixer belongs to that scammer,
moreover the quality of the website chipmixer makes it very different than coboguard's crap scam websites.
@stompix I have nothing to do with tether-mixer, but I just found amazing that a SCAMMER coboguard, comes here pretending to be a scam hunter, and say other websites are scam(while they are not, tether-mixer and bitmix workded for me). It's a bit funny no ? The scammer hiding in plain sight.....
Let see the bright side, since I came to expose coboguard the scammer,
he deleted tether-tumbler.com,
www.bitwhisk.io and other of his scam !
