A lot of the filtering of whom to show ads to is heuristics to try and target 'high value costumers'. Getting target with very irrelevant ads might just mean you are considered low value by most advertisers so you get served ads from advertisers willing to pay very little per impression.

I'd take as a signal your online cloaking is working as intended. I often get very random ads and recommendations in languages I don't even speak so I think my online anonimity fu is working as intended.
