Again... i say having a database with all the risks is better then having nothing.
+1
But realistically it seems very difficult, if not impossible, to set this up:
Apart from the DB leaking/surfacing (with funding required... and a treasurer, etc.) you need to get most of these people issuers/holders/scammers/anonimity super freaks to agree...
And there are not many guarantees it will solve the majority of people's problems, such as "free balances" and IPO funds being returned.
Perhaps it gathers steam, but it will take time and is such as complicated task that i see it as unfeasible, unfortunately.
Maybe there are other positive developments in the meantime.
I believe when this turns really out as a scam then the user funds are lost. But then the database is of no use for the scammer too. So getting a bounty at least for it could be a bonus on top. For the scammer(s) or someone other. Its not the best idea to reward a scam on top but the loss and trouble will be even higher for the shareholders when they dont have the db.
I dont know if we need most of issuers, shareholders and so on to agree. I mean what counts is the bounty that can be seen in the net. Who wants it back will give a small part to the bounty. Whoever dont need it doesnt need to give. But he shouldnt wine afterwards when the chance is gone without success.
Whoever give the db will get the reward first. So there maybe is a compete when more than one person has access. Maybe someone calls the datacenter and makes an employee an offer or something. Whatever. I dont think that the bounty has to be a crazy amount. If someone can bring the db and is willing to do so the btc bounty probably must not be too high. I mean for them would it be the same. Selling a otherwise useless db and getting something or have nothing.
And yes, of course i hope this will turn out good anyway so these thoughts wont be needed.
