I have turned it off again. It has too many adverse effects on machines that are online for short periods of time. Also the bulk of the spam I get is via a MTA that I have no control over, so greylisting only has potential to squelch 10-20% of my spam.
To avoid spam many websites make you fill out a CAPTCHA, or log in via an account at a corporation such as Twitter, Facebook, Google or even Microsoft GitHub.
I have chosen to use a more old school method of spam prevention.
