You have created 'auto import.....' can that not generate a date when the key is found and imported into the address book?
That could be part of the rules - must use auto-import to give a found date.
Perhaps bots are just going to be something to put up with?
Sounds like we'll need an entry process...perhaps, sign this 500 SPR transaction as your evidence of entry and the payout will go to that address, once it is used to transact with SatoshiNakamoto1?
This is getting more complicated by the second. lol
To have any validity, everything must be verified thru the blockchain and nothing else. (auto-import is just a simple qt-wallet function)
