Yeah I hate to say it but in their guidelines even too much censored cursing (especially in the beginning of a video for some reason) is grounds for demonetization for some reason.

No I totally understand where you're coming from as they 100% don't make it clear, but they just copy & paste their feedback. This is a screenshot of the self-certification option that makes videos have limited ads due to cursing. It matches your feedback word for word.pic.twitter.com/ydX1w21qLQ

As in, they probably thought it was borderline so just to be safe on their end they just put you into the limited ads category which is what showed up as feedback. It's SUPER annoying especially when curse words are cut out.
