= Hash Buster strings =

Not seen very frequently nowadays, but these were a staple of spams during 2002-2003 or so.

they'd look like this:

{{{
Blah blah spam text blah
http://www.example.com/link/
blah blah

oaynxwhgarpsottqxiloxlrwxp
}}}

the "oaynxwhgarpsottqxiloxlrwxp" block of gibberish at the end is the hash buster.
