Also check out the next snippet 1666 which performs a far more cryptic job of cloaking the text. Unfortunately with that solution using mailto: link, verbatim text remains in the source available for scraping. I think I'll try a combination of these two for ultimate transparency.

Realized if careful about passing different variables for email and title 1666 does entirely cloak the tag. The robots are smarter :/
