For the love of god just give us the tools for effective persona blacklists. With Google's constant changes to the search site and the difficulty in efficiently and effectively monitoring live search results via browser extensions, it's been at best hit or miss. Whether that comes in the form of some API that can be tapped to make a good extension or having it built into the browser, I don't care.

Google of all companies I would have thought would understand and respect the important of giving people the power over their own technology experiences.
