Not at all.
Well, ###. So if I have no idea what you're talking about, it means that every "MJ12" bot I've ever met is fake? :)
The access code is just so you can allow the real one and block the others. If I remember correctly, you sign-up for an account at MJ12 and during that process you choose an access code (example: lucy24) then he confirms via email. Then you use that access code in a mod_access filter allowing MJ12 bots that have the code in their UA string, but denying other MJ12 bots that don't. Then I think you need to specifically allow his bot in robots.txt as well (never did understand this part.)
This opt-in filter worked very well. I just discontinued it since I didn't utilize the seo data he offers, you may. He obviously uses your collected site data for business, but at least he is up front about it and offers a trade-off unlike a lot of domain-info-scrapers out there.
