I wrote about this back in July of 2010, and the problem has only gotten worse: http://don.blogs.smugmug.com/2010/07/15/great-idea-google-sh...
It's a crazy problem to have, but we haven't found a solution. We can't just disappear from all the various indexes and collections that these robots represent.
prerender.io does do most of what we do. A few things we do differently are keeping a pool of PhantomJS workers always available, killing HTTP requests that never complete, putting it behind HAproxy and logging.
