After 10 years I've finally given up trying to fight spam at my main email address. It has been abandoned completely, apart from a polite autoresponse that lets you know my new address.
To email me, build the address like this:
1: Start with rowan
So if it was the year 1956 the email would be firstname.lastname@example.org. You get the idea. :)
Incidentally, I'm already getting spam delivery attempts to email@example.com. This is the only place on the net that it's referenced.
