Back in the day, when Chicago.PM was just starting up, we were trying to come up with an Obfuscated message footer text which contained the usual unsubscribe info, for people wishing to get off the list. I came up with the following:

s??m, 2+02{0|/&{"E 0"+} *z&) 1, |%&|z\$,F-*F/".2"01Yfz&)&+\$Fe&01G+"1:
+4?,
s?^?|%&|z\$,F-*Yfz&)&+\$Fe&01G+"1 H\\%&|z\$, i"/) fAt,2v+\$"/9z+&z|B0H
+:?,
s?$?&1% {,}6 1"51 ;2+02{0|/&{";G _,/ *,/" %")-E 0"+} {,}6 1"51 ;%")-;G
+:?,
s?^,+?{,}6 1/&{"E 0"+} *"51 ;2+02{0|/&?,y,:-}"-9,\n"-|,&&print, #+-*/ 
+:?,

But for some reason, Majordomo choked on this. ;-)

We currently use the following, which is not too Obfuscated, so people can sort of figure it out:

undef$/;open      #   "moc.acipot@ebircsbusnu-mp-ogacihc" liam ,busnu 
+ot
STDIN,$0;print    #               mp-ogacihc/stsil/moc.acipot.www//:pt
+th
scalar(reverse    #                                moc.acipot@mp-ogaci
+hc
scalar<>),"\n"    #                   sregnoM lreP ogacihC -- mp.ogaci
+hC

Still get some people sending "unsubscribe" messages to the list, though. Sigh.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
