What I don't understand is, when I check some of those address, it seems there are some activities on it. How can it be, if the persons really lost their password and continue to receive money there ?
Well, maybe worth though to give a try... Where to find the wallet.dat of those address?

Not many interest there... Maybe a bad idea...  

A customer of mine needs liquidity to start a new web venture and is ready to sell several virtual assets of his company.
Namely: Exclusive domain names! (PM me for a detailed list)

For example: Webdomain.com.
The domain name has been appraised $400,000.00 by professionals (which is not a retail estimation but rather an entry negotiation start value) and has a huge potential in Webhosting / Registrar area.
I was thinking asking BTC300 for it?  Of course, through Escrow.

Is this something to start with?
