Omar keeps getting spam calls and he can't block them because they keep spoofing the number. Leo says it's called Neighbor Spoofing because they use a number that sounds like it comes from his neighborhood. It's illegal, but good luck trying to catch them. The problem is that spoofing a phone number is very easy. The caller ID is useless. And there's no real way to block them. He can at least complain to YouTube and they will pull his channel down since he's breaking the law by posting recordings of the calls.
Shannon is having issues with his neighbors getting a lot of robocalls from his number. Leo says that's called Neighbor Spamming and it's illegal. They can easily spoof his phone number in the caller ID to do it. But since it's done from overseas, there's no real way to stop it legally. The only saving grace is that it will move on to another number eventually.
