I’ve heard that it’s considered click fraud and that the advertisers sometimes Force the site to pay them back possibly a little bit extra as a fine.
Not too sure though. Personally I don’t really use it because the adblocking structure I have set up isn’t really compatible because it has multiple layers. I block the ads over the network through a network-wide firewall, I also block them through portmaster on my computer, and finally I have uBlock Origin in my browser. I also have adnauseam alongside of it and I turn off ublock origin for the sites that I want to autoclick ads on but almost none make it through the multilevel network filtering.
People will deny this but this is the only real reason for doing that. The other reason is copying apple, which isn’t really another reason as apple removed it for the first reason. Fairphone just went the extra mile to claim that headphones are wasteful, in essence they’re making an excuse to cover up their reason why and also trying to force others to do it as well.
