The only thing I’ll tack onto this is that with the introduction of Signal usernames, you still have to give Signal your number to verify that at least on some level, you probably are a real person. As someone with 5 different phone numbers, probably doesn’t stop spam as much as they’d hoped, but more than they feared, but at least now you don’t have to give that Craigslist guy who uses Signal your phone number, just your username. Is that the best method? I dunno, but but it is something.

This was my favorite thing about Tom Scott, it never felt like he was trying to pad the runtime for ads/algorithm. If it took 3 min to explain, it was a 3 minute video.
