MJ12bot
Majestic · SEO tool
MJ12bot only maps the links between websites, for Majestic's backlink index, and Majestic says it does not cache page content. It is a distributed community crawler with no consecutive IP blocks, so Majestic asks you to block it in robots.txt, not by IP.

If you block it
You ask the tool to stop analysing your site. It is your call, and your score does not change.
Allow or block
A group of its own makes MJ12bot ignore the “User-agent: *” rules. If you have Disallow lines there that should still apply to it, repeat them inside its group. To allow it, writing nothing is usually enough.
Allow
User-agent: MJ12bot Allow: /
