The boob that uses this javascripted obfuscation (by slicing up the URL
across variables and using concatenation within a variable) hasn't a
clue that the javascript or user clicking on a URL will still have to
eventually go to the destination so it will still get blocked.  Duh!
Nothing is actually cloaked by the javascript (it's just another means
of building up the <A> tag) and the URL string (even if it used a
decimal value instead of IP-dotted) still has to connect to somewhere
and that gets detected and blocked.  Slicing up a URL across variables
and concantenation within a variable is a child's ploy to obfuscate.
Apparently savitha can't even distinguish between an e-mail address and
a URL string.
