I agree, this only blocks legit numbers since they're spoofed anyway and next spam call will be an auto-generated number anyway (form a similar area code). My solution is to simply not pick up calls that are not in my phone's address book. I still get a lot of annoying calls, from a few a day to dozens. It's frustrating but I refuse to get annoyed, to keep my sanity. Most of the calls that I get are making an announcement in Chinese. I am not Asian and I do not understand Chinese. I've read somewhere that it's scam meant to swindle Chinese citizens in the US for money.

My wife received a call from a person who was angry at some phone scammer and started cursing her and telling her not to call anymore. My wife tried to explain that she did not make the call, that the number was spoofed, but to no avail, the curses continued until they hung up. I find this kind of breach quite problematic and don't really understand how it can proliferate to this extent.
