Tinder is launching an upgrade to limit awkward run-ins with familiar faces on the dating app. The online dating platform's new "Block Contacts" feature lets users avoid personal contacts, be it exes, family members or colleagues. "We're rolling out Block Contacts as an additional resource empowering members with peace of mind by helping create a worry-free space for them to spark new connections," Bernadette Morgan, group product manager for trust and safety at Tinder, said in a Friday news release. A recent survey commissioned by Tinder found that more than 40% of respondents have come across an ex partner on a dating app. The survey also found 24% of respondents have seen a family member or colleague on the app, and another 10% have seen a professor's profile.
