Then I guess you're in the wrong thread. ;) Best to stay on topic, thanks.
I don't know the extent of the arbitrage crackdown, but judging by the dot info backlinks to one of my popular sites, I'd say there was a significant drop. Checking the backlinks to one of my sites that had been plagued by so many scraper spiders my shared server crashed every evening, necessitating a move to a dedicated server, the amount of dot info backlinks is about a sixth of what it used to be.
To repeat what someone else said, that's not an MFA. It's a direct navigation domain. Searching through typing in a browser is called Direct Navigation, a subset of search. Don't feel bad about being confused by that, it's a common misunderstanding and many people, including some who should know better, make it.
