To poke my ugly nose in here, what you did was engage in a reputation building loan. Not only it is the wrong way to go, it is also grounds for receiving -ve rating. Clearly no one has the guts to do that to you, so be a dear and pull me in Level 2 so I can give you one. You're setting a bad precedent here and it will only encourage other to openly declare now 'Hey, the great Dooglus gave a rep building loan so we can engage in it now'.
If you truly believe Tspace to be trustworthy, why not give him a loan which is really risky, instead of some token amount? Give him 100 BTC and see if he returns. If you shy away from doing that it means you were only treading comfortable waters and angling for an excuse to provide trust which is almost as bad as selling trust.
I don't know whether he would steal 100 BTC given the chance or not. I suspect he wouldn't, but am not willing to take that risk. I was pretty confident he wouldn't steal 1 BTC, and was correct about that.
1 BTC is much more than he is accused of stealing from coinchat. Why would he steal dust from coinchat but not steal a whole Bitcoin from me?
