The email address as always been hidden and was only used for this forum (I have the whole domain to play with so I use different addresses for different sites which allows me to identify where spammers got my address from).
From haveibeenpwned.com:-
Bitcoin Talk: In May 2015, the Bitcoin forum Bitcoin Talk was hacked and over 500k unique email addresses were exposed. The attack led to the exposure of a raft of personal data including usernames, email and IP addresses, genders, birth dates, security questions and MD5 hashes of their answers plus hashes of the passwords themselves.
Compromised data: Dates of birth, Email addresses, Genders, IP addresses, Passwords, Security questions and answers, Usernames, Website activity
Hack was taken a step further on the weekend, where my account was logged into, the password changed then the email address changed to
sergun1646@yandex.ru. The email notification of this change included a link to lock the account, so at least the hacker shouldn't be able to use it now. I've also reported the email account to yandex.ru and their IP address (with date and time stamps) to their mobile ISP.
