Ugh, you're right. The political robo-calls have already started doing that to me, I keep getting calls from the Orrin Hatch campaign. If it starts happening with all of them, I'm going to resort to whitelist only. Auto-block all unknown numbers.
I made the mistake of donating during the presidential election and now I get loads. It's especially problematic since each Senator/Rep has a separate opt out list - every time I tell one to stop a week later a different campaign is hitting me up.
