Tinder is taking another step to help notice red flags about potential dates. Tinder users will now see a background check tool in the popular dating app's Safety Center. For a small fee, users can conduct background checks through an agency that searches public arrest records, convictions, and sex offender registries across the country. But, experts also caution this isn't necessarily a "catch-all" because research has shown that sexual crimes are often not reported to authorities. Would you use a background checking system on a dating app? Do you have a dating disaster story from meeting someone through Tinder (or other apps)?
