Update: Deleting the text of a node with replies is frowned upon because it obscures the context of the replies. One option if you want to retract all or part of a node is to enclose the retracted text in <strike> tags.

How about:

#!/usr/bin/perl -w

use strict;@_=("\x4a","\x20","\x50","\x2C");$_="6=6IZ,3AA>&]Z:'=Q,C-W<
+6DT,GEW<0

Update:
(1) Removed example that doesnt use strict/warnings;
(2) Modified current code (cosmetics, some regexes, value of $q, and added one sub).
