Grindr appears to ban profiles of innocent individuals who merely reply to offenders to protect themselves but appears to take no notice of serious crimes or insults on behalf of offenders. There is absolutely no policing, particularly with regard to foreign languages. This needs to be improved, otherwise the app should disappear from the market.
Attached you'll find an offender insulting his interlocutor, who insists on wanting to know their origin (although the person is multicultural, with a mixed background), which underlines racist or ethnicist behaviour on behalf of the offender.
