Blacklist based on voted category

When I classify/vote on a webpage in a category that is currently blocked in my networks, it would be great if it would also be automatically blocked in my networks, either by temporarily adding it to the blacklist, or by using the voted category as my preference.

For example, if I indicate that website xyz.example.com contains Nudity, and I have blocked all pages in the Nudity category, this setting would then either add xyz.example.com to my blacklist, or just block xyz.example.com based on my vote. This would allow me to more easily block this page until the voting process for it is complete.

I assume the same process could be applied for whitelisting a page on categories that are allowed, but I'm not sure how this would happen since I'm not familiar with that.
