Yeah I am okay leaving it to mods. But I think in this particular case if the mods themselves are posting affiliate links with no indication they are getting money for each use, that seems like misaligned incentives.

There were some subreddits that would have stickied posts or something that allowed affiliate links, but that aggregates it all into one place and also lays it out clearly for whoever visits.

My main concern is not that someone is making money, we all gotta eat, its just when people aren't aware they are potentially being manipulated for someones benefit.
