Maybe I missed it, but i'd want concrete proof that the premine was destroyed - just saying that the coins were sent to an "unused" developer address doesn't cut it for me.

40 million coins were sent to the address "PayProCoinPayProCoinPayProCoj6ngcU" on July 24th (block 13636). The other 40 million premine coins weren't destroyed, nor was the approx. 3-4 million instamine.

Were the coins really sent?

They can be seen in the block explorer: http://blocks.paypropool.com/address/PayProCoinPayProCoinPayProCoj6ngcU

If you do not trust the block explorer, launch & sync the client and in the console use these commands: [these are from memory, might be slightly incorrect, I've never installed the PayProCon client so I can't check]

getblockhash 13636
getblock XXX (hash from last command)
getrawtransaction YYY (transaction from last command)
decoderawtransaction ZZZ (transaction from last command)

If you don't trust the console interface, get the code audited, but a good audit is likely to cost far far more than your current or future PRO balance.

Is this address really unspendable?

Assuming there are no nasties in the code, then yes the address is effectively unspendable. The address was created as the string "PayProCoin" repeated as many times as allowed for an address ("PayProCoinPayProCoinPayProCo"), followed by a 6 character checksum which causes the address to be valid (j6ngcU). It is not practical to find a private key which matches this address. If you think you can find one, good luck, but I'd recommend you instead try to find a private key which matches the similar Counterparty burn address (1CounterpartyXXXXXXXXXXXXXXXUWLpVr) which has over 2000 BTC waiting for you and is equally impractical to find.
