Honestly, it is either because "mature" themes or that people feel comfortable with writing with fellow adults (in a 1x1 setting). Mine is 18+ largely because the latter, but most people do 18+ because of mature themes like smut. You can't RP smut on the forums but you can do so in PMs, therefore people tend to lurk there for partners, which in turn causes a surge in interest checks from people wanting to get their freaky on.

As others suggested, I'd suggest checking the other sections on the guild since 1x1 is more or less no man's land filled full of 18+ and smut checks. Maybe try looking through the casual section since people tend to congregate there more than other sections.

That.. That might actually work out. 

I mean I could honestly try posting interest checks in every single catagory of interest-check forums and such.
