Fortunately someone has marked it on the ground that the account has been compromised or changed hand even though I did not find that the OP has changed the password and email which has been a strong reason for proof of account sales.
I don't recall how long BPIP has been storing seclog data but there may be a possibility that it didn't catch a password/email switch. I would say, though, that the huge gap between posts and the switch in logic is a massive red flag. Unless you're an amnesiac, would you say that you were a new user
twice?
