I don't know whether he's married or not, but I never told my ex-wife my passwords for eBay or PayPal. If he died, I would be surprised if anyone picked up the business.

Of course, if he's gone, a few negs aren't going to hurt him anymore. I feel sorry for the buyers who may have lost money, although PP offers some level of protection. At least some of the buyers have responded with concern and have assumed something must have gone wrong.
