I wouldn't go as far as saying "scary ads about clowns" is arbitrary as many people truly are scared or even terrified by clowns. Contacting Fandom still seems reasonable, even if the request is only taken as feedback. CSS is an option though perhaps they don't wanna hide all ads. In that case, contacting Fandom is still a better option and, dependent on the ad and wiki, they could remove the ad from a wiki (if not altogether).
