There are two things I want to ask here:
1. Does EZ0010 overpay for copper members?
2. If so, why is the account status not a copper member?

I thinks EZ0010 did not use its main account ^{[copper member]} to return the bitcoin theymos randomly sent to him because theymos said that the final recipient was somewhat anonymous so it is unlikely to get the bitcoin back.

But, luckily EZ0010 got bitcoin back on record and that made it a bit viral on forum especially in meta based on the amount of merit it received in the last 24 hours. Thanks to his honesty, he has earned 50+ merit, that's probably not worth the $1000 he could spend on a year-end party dinner with his friends. But the important lesson here is that in the dark there must be something of value, even if it doesn't emit light and that is a reflection of the attitude of the EZ0010.
