Engagement might be higher and therefore more ads to show. I definitely participated in groups quite a lot some time ago. I’ve always used an advertisement blocker but I could imagine I should’ve seen many from how many posts I read. Also, these posts can show up in your news feed where ads are always showing up. But... the groups I participated in the most usually involved people with differing opinions and thus why engagement was high. Everyone had to argue a lot.
