just a couple counter examples I wanted to point out:
giantbomb.com (ads + subscription only content) 4chan (I would like someone to explain it more deeply to me, but I think they run their own ads, do they use an outside service?)
giantbomb.com (ads + subscription only content) 4chan (I would like someone to explain it more deeply to me, but I think they run their own ads, do they use an outside service?)
Having users pay for ads instead of third parties keeps it quite neat and generally quite safe, but I don’t think 4Chan itself is profitable.
