Block Content config?

Hey there,

I have got a problem. I do not want to allow any html content in my CK-Editor. At the moment I am using the "config.extraAllowedContent" tag to allow content. The problem is that I am not able to type everything I want to allow there, because we have got very dynamic content.

In fact there is exactly one tag I want to block. So is there a way to do so? Something like "config.blockedContent"? I think it is hard to allow every content but this one  instead of just blocking one.

Greetings
