That's super interesting. I thought it was the other way around. Whenever I saw 18+, I thought it was suggesting that there will be mature content, which I thought suggested that there was going to be smut. The idea being that they didn't want to do smut with a minor. I really am giving them too much credit.

Personally, I do an 18+ looking for mature non-smutters, but that may just be me, I've gone through a few who don't list 18+ in the title of their thread but in the rules, and found people who are looking for plots and are mature, but maybe I've just been lucky so far.
