What do I need
I have registered more than 10 Discourse forums on Win10 browser and Android, such as F-droid, etc.
But I have forgotten my username and password, and my mail has been banned by the mail provider.
Don’t use spam-accounts. That is the real reason. But in situation like that you should try to connect the admin and explain that. Or create new account and try to get those connected.
