I’ve been opting out of every single one, but some companies are assholes and make you send it in through a written letter (Meta) or worse, automatically accept it if you’ve even just used the app/site/product after they send an email to you regarding changes. The fact that massive corporations also say all matters must be resolved in small claims court and with mandatory arbitration with the company’s arbitrator is incredibly illegal sounding. Fuck you AT&T. They were the company who fought for revoking arbitration rights in contracts. The Supreme Court decided it was legal.
I got banned from (later re-added to) r/neopets… a person was seeking help about getting back their old account, and I said they’d know which email was used because the MASSIVE neopets hack is on most people’s identity theft reports and online security data. They don’t want scammers to know about the hack, even enough over 40,000 accounts have been already stolen and a group in Brazil is making over $20K USD a month selling the rare/limited digital items, for real money, to those who don’t want to grind.
I pleaded and they let me back in. They take it very seriously.
