spamblock

Noun

 * 1)  Text inserted into an email address in order to make it invalid, though still readable to a human being. For example, in "jsmith-[AT]-example-[DOT]-com", the "@" and "." symbols have been replaced with literal text to prevent automated spambots from finding the email address while still leaving it readable.

Verb

 * 1)  To obfuscate (an email address) with a spamblock.
