For a long time, the Internet has been replete with blocklists and reputation scores cultivated by admins who had the means to track such things. And ad-blocking software/DNS often gives users the chance to tap into those bad reputations and protect themselves.

However, there is nothing preventing function/scope creep of these blocklists into things they should not be. Political bias, censorship, morality policing will trickle into blocklists. Furthermore these false positives are quite onerous for legit businesses and customers who sincerely want to connect. I've connected again to an ad-blocking DNS service, and many people may subscribe to filtering services, or simply be involuntarily subscribed, in the hopes that their Internet would stay usable, and scam-free.

I suppose this is the price to pay in low-trust society (wild and wooly Internet). I wonder if the Great Firewall of China obviates the need for their citizens to throw up such protective measures.
