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?
