. . . btw this mess was about 4 btc (four!)
Agreed, Roger damaged his own reputation, the reputation of MemoryDealers.com, the reputation of BitcoinStore, and the reputation of blockchain.info all over 4 BTC. Seems ridiculous when you look at it that way.
Clearly NetHead was wrong in his actions, and by returning the 4 BTC could have prevented all of this, but that doesn't justify the damage that Roger did over that same 4 BTC.
