Why would someone who has so much bitcoin need this kind of a loan? Why would you think it would be a good idea to lend someone with tspacepilot's trading and trust history 1BTC worth of an altcoin?
I don't think he needed it. I loaned him the 1 BTC worth of CLAM as a test to see if he would pay it back, like you suggested. I have no reason to believe he isn't trustworthy. Sure he has some negative trust ratings but they mostly seem to be from you or suspected sockpuppets of yours. You seem to have some kind of a grudge against him.
What I do have however is what this certainly looks like. This looks like that this is an example of selling trust, either for the entire 1BTC amount (assuming there was no loan, only a "repayment"), or for whatever the interest amount was (assuming there actually was a loan). For a number of reasons that I am not going to call you out on (yet), I am leaning towards the former. The selling of trust is highly frowned upon within the community.
I loaned him 123 CLAMs and he repaid it. Other than that nothing of value changed hands. I wouldn't "sell trust" under any circumstance. Call me out on whatever you like. I have nothing to hide.
I would ask you, are you really willing to stake your reputation on this person?
I'm not staking my reputation on him. I left positive feedback after he repaid the 1 BTC worth of CLAM I loaned him.
I think it would be advisable to remove the positive rating you left on tspacepilot and to remove the exclusion next to my name. Both of which I think it is reasonable to conclude were sold.
I don't think that's a reasonable conclusion at all, since (a) it never happened and (b) there is absolutely no evidence that it did.
You can't imagine why tsp would take a 1 BTC loan when he has 5 BTC already, and yet you think it's somehow possible that I would risk my reputation selling trust to tsp for 1 BTC?
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.
