I don’t think any posts here are based on profiles of the users. I have almost zero information about the audience for any post here. That would be fine under my proposed ban. It is similar to an ad in a newspaper: the ad reaches the kind of person who reads that newspaper, but I have no fine-grained control.
And, almost as importantly, I can’t limit who sees the ad. One of the big problems with these platforms is that they can give two people completely different ads for the same target, with contradictory information. If I put an ad in a Mastodon post, anyone can boost it and anyone can see it. If it’s something divisive aimed at the biases of a narrow set of people, it will be visible to a load of people with the opposite biases. In contrast, on Facebook I can buy an ad with pride flags that targets gay people and an ad with homophobic messaging that targets far-right people, and neither sees the other unless someone goes to the trouble of screenshotting it and then shares it and the algorithm doesn’t suppress it in the other group.
