It's like all computer security really. It works now, so for the
moment so we use it until we're forced into something more difficult in
response to whatever's going down at the moment. You can also use
javascript encoding and that will work until spammers add a javascript
interpreter. But if they did then you could make a page that could
really chew up spambot cpu cycles.
