Obviously we would completely purge any public keys for accounts with zero balance and with no aliases.
Is there any way this could lead to a Sybil attack?
If it is possible to create a "new" account *with* a public key (as an atomic operation) then this shouldn't be a problem (isn't that coming?).
no i think hes right, and i was wrong. you didnt quote his edit to add the blurb about merchants storing old accounts. things could get very hairy and mixed up that way.. kinda dangerous the more I think about it, to completely purge. wed have to well publicize the risk
would also have to handle the upcoming ability to transfer your effectiveBalance to lease your forging power out. Wed either have to track that as well or just make it kick back to account owner upon pruning
