Unless you do it the old way, using robots.txt, you can't rely on all
spiders obeying - actually, I don't fully understand why MS invented
this particular META tag, except possibly for people with only access
to part of a site (robots.txt has to be at the root level).

Javascript can be fatal to spiders, as they cannot follow links obfuscated
by it; not that they would want to follow links to themselves.
Also, in some contexts, I think it is possible to use pure HTML and some
search engines may encourage this (others may consider it theft of service
to bypass their home page, so check first).
