Edit - The only "loan" on the forum here is to snakey. And I'm not paying him the 10 eth or so, after I found out he was pinkman123345. So he backstabbed me and he wants me to pay him a couple grand? Bullshit.
A thought:
If you have an outstanding "loan" to pinkman12345, a good place to start for karma-cleaning would be to repay what is owed by him to his victims or assist in debt recovery since you have worked closely with him in the past.
ill gotten gains never go far, but here you have a chance to make ill gotten gains not so ill again (atleast partially).
All the money I made off the ICO that pinkman got "scammed" was around 4 eth, and I repaid him 5 eth before he backstabbed me. I don't see why I should donate the remaining balance as the money I earnt accidentally is already gone.
