I also received a similar email a few months ago, but it was in Russian instead of English and suggested using Google translate. However, it wasn't containing any of my passwords; it was a simple threat demanding $1000 in Bitcoin. Ignore it and move on; change your passwords and secure your Bitcointalk account, which is vital. I've also used the website haveibeenpwned.com and have suffered plenty of leaks. I've changed my password multiple times, but my email is still being targeted. Is there a way to save it, or should I just dump it?
if you change your password then you are safe from that threat, so it's better to block that user's email so you won't receive that message again, but if you feel worried about the threat then it's better to change the new email and just ignore the email long time if no account is linked, I don't care about any threatening messages on emails because if he manages to hack my account then why doesn't he just steal it without begging to mail $900 to his address.
