they've been looking at javascript for ages. they even seem to follow the links contained in it.
if you really want to hide it then i would do something like this... put the javscript inside a function in an external file, and then just call the function from your page. or call the function when the page loads or something like that - then you won't even need to include the

<script> </script>

They look at the code and try to find links, they just don't run the code like a browser would.

I'd imagine its not passing any link juice and thus wouldn't get you in trouble if it was a bad neighborhood, sold, advertisement etc.
