I still see people who everyday lose there email to spam due to stupid ways they go about there everyday life. Don't write email@example.com. There is no reason to ever do this. There is also never a reason to make it a link. Instead write your link like someone (at) noreply (dot) com, or something similar to this. Or even better, just make it an image. A user will be able to tell the difference between the two, and you'll save yourself a lot of trouble from spam.
