It's interesting how the negative examples all look like mobile game ads.

Which isn't an accident - mobile game ads are tuned studiously on consumers actual preferences and not the preferences of designers. i.e. the people that are likely to spend actual money on the product/service being advertised to prefer the ad being portrayed here as bad.

Bluntly, being able to sidestep the whims and fashions of graphic designers is proving to be a major feature of the AI revolution.
