This is my first time seeing a site allow you to ban individual third parties. Is that a best practice for GDPR? Most site's I've seen only allow you to see what they are. With that said, obviously clicking 300+ checkboxes instead of having an "uncheck all" is absurd. But, I can see how a site that has been around for years could have 300+. I just cleaned up a website the other day that had 50 (we pruned it down to 20 after 30 of them couldn't give us info on their GDPR policy). I'm also concerned about the blanket statement that companies that say they care about your privacy don't. I've told people I care about their privacy and I actually mean it... :(
