Here are a few things I've learnt about how to reuse Tinder after a ban.
1. You can buy a very cheap smartphone in Akihabara for 4000 yens or even less.
2. You can also buy a prepaid Sim card by Mobal which can give you a new phone number every month if you like (+voice+unlimited data).
3. Submitting your ID doesn't ban you again since they don't keep the data.
4. Even if you register with a bogus age, the ID validation will work because they only check that you're above 18 yo.
5. Obviously, GPS location isn't checked either.
