How can you tell if an MJ12 is real or fake?

Isn't MJ12 the one where you sign-up to get SEO data (similar to GWT) in exchange for letting them crawl site? If so, they give you an access code to allow only their authentic bot. I did this for awhile but didn't see the benefit so I stopped allowing them.
