All HashFast customers appear to have had their email addresses leaked today by the company itself.

Please ensure:
1. Images are turned off in your email client to prevent ip phishing attempts.
2. Reverse email lookups do not reveal your delivery address.
3. You do not open emails that appear to be phishing attempts.

Disclaimer: I am not a paid employee of HashFast but was instead selected to answer questions for them here on bitcointalk -- so please don't emit venom in my direction.
