Look, I know this is a late response and all but this is serious: it’s feeding a mogwai after midnight that turns it into a gremlin. Gremlin feeding times have no impact on their behavior.

Ad algorithms might be using more complicated analytic combinations than just “similar sites” as a qualifier. Maybe you’re a fan of a product or show (or combination thereof) that typically map to right-wing readers or likely converts.

If they’re getting (just making this up) a 5% click-throughs rate with this targeting vs 2% with just similar-site matching, then they probably don’t care about a high rate of views by left-wing users.
