In my /etc/hosts file in macOS Mojave 10.14.6 I have
127.0.0.1 someotherdistraction.com
127.0.0.1 https://www.tinder.com
127.0.0.1 https://tinder.com
127.0.0.1 www.tinder.com
someotherdistraction.com's redirect works just fine - why doesn't tinders? I have also tried hard refresh/clear caches to no avail.
http://
etc. You do need to cover all eventualities on domains that have CDN or other outlying structures, so you might need such aswww.tinder.com
tinder.com
cdn.tinder.com
or a slew of other related domains.
