Tinder has teamed up with Garbo to offer background checks for users. You get 2 free ones, then pay about $3 for each additional search. The results show any past violent arrests and convictions as well as sex offender registration.
This is great, but we really need a review site for dates. I need Yelp reviews for dudes. I'm trying to figure out why Trent as 12 ex girlfriends from the past 2 years.
