I used to support testing the adblock solutions from Pixeltris some years ago when Twitch actively starting fighting adblockers. It turned out the only reliable way is to use a proxy or VPN of a country that doesnt serve ads via amazons ad system. Mostly small countries where it’s not worth place advertisments. I am using eithe czech, polish or Luxembourg IPs and usually dont get any ads this way anymore as there are no corporstions using their af service.
