The worst offender for this, in my opinion, is Wikia (sorry, "Fandom™"). There is zero attempt to make the autoplaying content at all relevant to the wiki in question, and it generally isn't even advertising anything, it's just... crap. It seems like they're desperately trying to believe they have a social network on their hands rather than a collection of disparate knowledge bases, and they're trying to sell this non-existent 'fandom' culture to visitors.
