If they don't know your real IMEI, how can they permanently ban you? They don't ask for a copy of your social security card or anything.

I can see why you might want to permanently ban them, though. Blaming you for a bug in their software.

It is absolutely NOT a bug in their code. The relevant API is here: https://developer.android.com/reference/android/telephony/Te...

If that firewall app is making those methods return anything other than null or a truly unique ID, then they are not a compatible android device, and someone using such a device is not in any position to complain when apps behave incorrectly.

It's worth mentioning that it's not required for the return value of those methods to be the IMEI, but it is required to be either unique or null.

They don't ask for a copy of your social security card, no, but I have to have a cellphone tied to my account and I only have one of those.
