I never click on ads. Never ever. I get that every ad doesn't need to be clicked e.g. videos that mindlessly show you a product. But atleast there is no direct feedback going back on those in terms of ad placement effectiveness/click-rate etc. They can keep burning their money showing ads - I just won't provide them any feedback on whether/where their money was wasted vs well spent. Also the best way to kill them is for lesser and lesser people to click on them.
