I completely agree with you, but this is a straight up ancient problem, and if you don't believe me, you can ask Scaurus, maker of the best gaurum in Pompeii. The "get crowd's attention and monetize it" strategy has been around since the invention of begging. It's a fundamental strategy in any large group of people. The bigger the crowd, the better it is as a strategy. Sure, social psychologists and marketers are out there making better an better spam, but that's just tuning. As long as there are large groups of people and a way to communicate with them that's even slightly cheaper than the return, it'll never stop.
I suspect there is no solution, but it's interesting to consider some. What would a society look like if you somehow forcibly limited the number of people you could contact?
