Which data leak is likely responsible?

I don't think the bitcoin address is relevant because it changes in each spam email. Gmail has intercepted around 15 spam emails. It's not the exact same wording as the OP's email but it's along the same lines:



Further down in the email, it quotes a Bitcoin address, but in each of the 15 spam emails that I had that is worded exactly in my quote, the Bitcoin address was different.

Aye we've had similar before but never stating actual name and full address, usually just sent to the email name.
