I obviously don't know what you scrapped, but can't you salvage the content by having the young man's older brother visit? That way the babysitter can interact with a young adult clearly 18+
Saying this 'cause while the "babysitter seduced by married couple" trope is of course perfectly fine to mine for material, it isn't the same as being jostled or "playfully harassed" by your "innocent" young charge (or in this case, his clearly 18+ brother).
Well, technically speaking, rule 7 does not say "They must be 18+ with a picture of the ID/passport", even because actually in some States in USA then would be 21+, and F95 tries to strike a compromise.
If they were only to give access to stuff that is fully legal everywhere in the World, then they could as well close the site, since there are countries where any naked representation, sexual representation, or even innuendo, on TV, games, photos, is illegal, even of people well above 18 or 21.
But is true that in some countries, any representation in any and whatever form, even if you draw it yourself by hand on a piece of paper with pencil, of a minor involved in sexual activity, become pedopornography, even if they are above age of consent.
And in some case, even what is sexual activity, can become in the extreme a matter of contention, some would say that any picture of anyone below 18 (or 21) that is not dressed is pedopornography - even a swimsuit or a dress can be considered too sexualised.
In some country were the age of consent is 14, even a couple of 14-17 years old, can "do it" without legal problems, but if they take any picture of themselves that can be considered "sexualised" (which does not automatically mean making a porn video), even without sharing it with anybody else, would be committing a crime, most often, without realising it.
