To be fair, the site acknowledges that they can't control what we do privately, so whenever I see that a 1x1 intends to engage in adult content I assume that the RPer wants to conduct the RP via PM or elsewhere, but maybe I'm giving them too much credit.

Oh, you are giving too much credit. Waaaaaaay too much credit. Back on the old Guild, after Google ads were taken away due to them finding some objectionable content (it wasn't even a 1x1 smut thing, it was something old in the Spam section), a bunch of us went and searched for smut and so forth to bring to the attention of mods. Just between me and Elendra going smut hunting we must have found well over 100 blatant smut threads in the 1x1 section, plus tons of interest checks with really shady things (lists of kinks and explanations of some of them, for instance), and that's just what the mods hadn't already nuked in the past.

There are many people who blatantly disregard the rules, or maybe never read them in the first place. It's true that almost all of the smut 1x1 interest checks I've seen in my time on RPG have said they want to do it via PM or off-site, but there are still plenty who don't care about or never read the rules, which causes things like what Brovo mentioned about people just assuming adult content is allowed.
