I started receiving e-mail spam to a unique randomly generated mail address that I have only used to register on Bitcointalk. Since my address is set to private ("hide from public"), the database / server might have a security problem somewhere. Admins, could you please check if there's been any suspicious activity?
Does anyone else have evidence for a possible data leak?
Old news. There was a hack last year and a hacker got quite a huge chunk (if not all) of the forum's database. It has been floating around the internet for a while now.
