So a website you don't like you would ban for everybody else as well just because you decided that it is merely marketing crap there making you nauseous. So you then conclude it should be banned for everyone else? How do you think the world would look if everybody had the power to ban things with similar reasons? We'd have nothing left in the world. Scary.
Why not just serve a special list to all android users from India that contains the top 100 most popular Indian websites (https://www.similarweb.com/top-websites/india/)? Surely users will stop using that browser when they can't visit those websites anymore because those are now blocked instead of the ads.
