Lots of stolen pass sites out there unfortunately. Generally most of the logins don’t work but they put a few working ones mixed in to keep people searching their site. If you noticed the site is full of affiliate links. Their hope is to attract users with the promise of free logins but their real goal is to have the users give up on finding a working password and signup for the site (from the affiliate link).
Definitely falls into the “shady” affiliate category.
