first remove your negative trust
Did you even read the thread?
Yes, I've read. And I see this guy had negative trust one week before opening this tread.
"Tomatocage 53: -0 / +28(28) 2014-12-12 0.00000000 Alt of Raveldoni."
And, as you can see, Tomatocage left that feedback on December 12th. This thread was made on the 8th. When this thread was made, the account was still worth something since it didn't have negative trust yet.
Use the trust rating wisely, see the untrusted feedback too. In this case there was warning signs from 2014-10-19
See this thread for details on how to better utilise the trust system https://bitcointalksearch.org/topic/edu-lenders-use-the-trust-system-its-there-to-help-you-897570
He is gone after all his sockpuppet accounts were caught. There is a thread in the scam accusation section about him.
Yeah, that untrusted feedback from sellersguild is when I first caught onto this guy and started looking into all his alts. At least this is the only scam he ended up getting away with under those accounts.
