Is there a way to ban an e-mail address or pattern?

[Dravere]

I'm searching for a possibility to ban the registration with a specific e-mail address or even better would be to ban specific patterns of e-mail addresses. Is this possible with NodeBB? I'm unable to find anything. If not are there any known plugins that can achieve this? So far I wasn't able to find anything.

Thank you in advance!

@Dravere Do you mean like a "e-mail blacklist"? I think there is nothing like that yet.

But that would give a great new feature. And I think it's not hard to be implemented in NodeBB because there is already a blacklist for IPs.

@jtsimoes Yes, you could call it an e-mail blacklist.
