A few years ago I felt like I should contribute something back to SO (having used it plenty of times for research), but somehow I got routed into a "gotcha" UX where the site would repeatedly tell me that my previous action was against the rules. It felt like being trained via shock collar. I certainly appreciate the goal of maintaining quality in questions and answers, but I hope there are better ways of getting there than what I saw.

Note that the experience I have didn't appear to be human-initiated: I understood it as an automated "feature" of the site itself, a sort of guided initiation process. Maybe that process trained some people a bit too well?
