Not sure if you're talking about Adnauseam, but this is basically the lawful evil version of the extension you're describing. https://adnauseam.io/
Adnauseam actually clicks on every ad in the background, otherwise it's just a wrapper on uBlock Origin.
Yes! That one. But we need it for video ads as well now.
Ads are an evil that must be removed from the internet, and draining the wallets of companies using ads, without upside, would make them place less value on them.
