Banning Mac Or ISP Address

Let´s say some member has a dynamic IP address and has access to disposable e-mail addresses. Is there really no way I can stop him? The Internet Service Provider is always the same, also the Mac address. But there´s no option in the admin panel to ban those.

Any ideas on doing exactly that or is it impossible (currently)?

Thank you.

There should be three options to ban a member: Username, IP address, and email address.

I know but none of them help to keep people off permanently.

You will just have to continue banning each new account created by this member. You could set up registration where an administrator has to activate the account.

Thanks for your reply.

If there´s no alternative topic is solved.
