selling/buying names isn't Always scam, i admit i have bought and sold names in the past, and i didn't think any moment about scamming someone ( my rule is: don't do bad things to others, because you wouldn't want that to happen to yourself either), anyways, my advice is don't trust everyone, if this person seems to be a good friend, sure go ahead, but don't do this with randoms that you have never seen before, don't risk it
