Is there any way you could add a blacklist mode to the plugin? Because I don't want to add every single block to the config.

This can probably be classified as a duplicate of #95, so I'll close this issue as such.

With that being said, I don't think you're actually going to want a blacklist mode. You'll realize fairly quickly that your blacklist won't provide much more benefit over the current list functionality. I think the appropriate solution is really just allowing for tags in the block list, which is planned.
