I definitely feel the same way as optimist. It's just the right thing to do to verify any NP$ that you didn't know were coming, especially before you spend them. I've had a couple of such incidents and always returned the NP$ to the person if it was in error, whether it was 10NP$ or 100NP$.
I'm very glad to see that NP respects it's members enough to look into these things and recover the lost NP$ for websoft. Whether Psycho did it or not (and I have to say the evidence looks pretty bad), the fact the admin spent a great deal of time in getting to the bottom of things shows a lot of caring on their part. Most sites wouldn't bother.
Even if Psycho is a victim as he says, that is standard procedure for any business. If you get stolen merchandise, even if you bought it with a bill of sale and are completely innocent, the merchandise is confiscated. NP did exactly that and returned it to the rightful owner. Whether it's fair or not does not come into play. We were in the flea market business back in my younger days, and I saw this scenario a few times. People bought an item for 100's only to find out the next day that it was stolen when the police came looking for it. They didn't go to jail (because they bought it without knowing), but they lost the merchandise and the money. The lesson here is to make sure that the NP$ you get for something you didn't know are legit and if they aren't, to return it, not spend it in the next 5 minutes, which makes it sound suspicious indeed.
