It is also possible to simply deny prefetch requests

prefetch". (See [2])
I've e-mailed Google's feedback address to ask for more details about
the prefetch behavior, which is woefully underspecified in their 'Help
for Webmasters' page[1].
If it really behaves as the Mozilla prefetch that they reference as
documentation, then there's nothing to worry about, since we don't
specify any dangerous URLs as <link rel="next"> or <link
rel="prefetch">. If it doesn't behave that way, then more information
would be helpful in deciding whether rejecting prefetches is necessary.
