I imagine a similar thing is happening in the phone space too. Scam calls are 99% of the calls I get on my cell phone now, and probably close to that for "revenue from calls" that the providers are raking in. If I could spin up my own cell network like I could an email server and a domain, you bet that the big cell/telecom players would "blacklist" my domain for "spam" the moment they caught whiff and instantly make it almost useless, same as Gmail does.
