It definitely is a hard problem, and I agree that there's no way that this could happen without regulation. I could imagine it being enforced across all companies that reach a certain scale. Below some scale threshhold the damage that can be done through bad actors is minimal anyway, at scale, it can alter elections. I think another side-effect here is that it could turn the act of buying advertising into an arms race, where those buying advertising are forced to monitor their competitor's advertising buys since they know that their competitors are doing it to them.
