Wondering how investors receive STX

#1

As far as I understand investors will receive STX in October. But I don’t know how Blockstack PBC processing it.

Investor submit his/her address in the Sale STX Website. I know it. But what if (s)he submit a wrong address? Will Blockstack PBC reverse the transaction to help his/her get back STX?

Does Investor has option like “send 1 STX to address ABC so (s)he can verify everything is ok then (s)he will email/or submit a form with a picture of the successful transaction to tell you send all STX to address ABC”?
