how to get tinder after being banned

I'm sorry to hear that. Tinder usually bans accounts due to violation of their community guidelines. However, unfortunately, the process to recover a banned account is not straightforward.

You can try to appeal the ban by contacting Tinder Support, explaining your situation honestly, and requesting them to reconsider the ban. But the chances are quite low.

If that's the case, you'll need a new account. Remember, you'll have to use a new phone number and email id that you've never used with Tinder. Also note, new installations need to happen on a new device or by using a way to change your device id, since Tinder can trace devices for reinstating bans.
