spamblock

   [poss.  by  analogy to sunblock] Text inserted in an email address to
   render  it  invalid  and  thus  useless to spammers. For example, the
   address     <[email protected]>     might    be    transformed    to
   <[email protected]>.  Adding spamblock to an address is often
   referred  to as munging it (see {munge}). This evasion tactic depends
   on  the  fact  that  most  spammers  collect  names with some sort of
   {address  harvester}  on  volumes  too  high  to de-mung by hand, but
   individual  humans  reading  an  email  message  can readily spot and
   remove a spamblock in the From address.

   Note:  This  is not actually a very effective tactic, and may already
   be passing out of use in early 1999 after about two years of life. In
   both  mail  and  news,  it's  essentially  impossible to keep a smart
   address harvester from mining out the addresses in the message header
   and  trace  lines. Therefore the only people who can be protected are
   third  parties  mentioned  by  email  address in the message -- not a
   common enough case to interest spammers.
