Imagine I have a page on my website that I don't want to be followed by robots. So I put a
rel='nofollow' on every link to that page.
Now imagine I have a form on another page which action is a link to that page. I heard that search engines try to post forms. If it is true, they will reach a page that I don't want to be indexed.
Am I falling into paranoia? Do search engines really try to post forms?
