I went to look at what ads I was being served and then remembered - I don't see them anymore because I became a supporter.I am happy to say that I have trained myself to not even look "over there" and I have no idea what ads run on my feed. (Your post had me look, and I was happy-ish to see that it was just some silly ad for a bank.)
I'm tempted to log out and see what I'd get - I bet it's the big old ugly Temu ad that has been following me everywhere lately.
