Doing a bait-and-switch is potentially artless enough to be risky; but I suspect that there are a bunch of p-hacking minions of darkness combing through the tailings heap down by the data mines, looking for correlations between patently innocuous interests/behaviors that anyone will be happy to let you target ads for; and the characteristics they care about but can’t be so impolite as to outright request.
Basically “strip mine https://stuffwhitepeoplelike.com/ for interests and activities; have a sincere explanation that your real estate and financial services opportunities are just super popular among roller derby enthusiasts, and what’s wrong with that?”; except probably less comically overt and with at least some attempt at statistics.
