You know, the forum is not limited to write only mode, you can also read the posts. And it happen that many in this thread answered your question and solve the none existent mystery you're trying to point to.
There's near to 20,000 games available, with most of them being updated many times before completion. Neither uploaders, not moderators or staff members, have the time to play them all, even less each time a new update is released. What mean that, yes, there's
few games that escape their vigilance. And
I already explained, in this thread, how and why it happen most of the time.
Is also to note that the rule 1.7 do
not target underage characters, but the "nudity, sexualization or sexual/erotic activity involving
prepubescent character(s)".
emphasis is mine.
And from the quick look at took at some of the games you linked, I haven't seen one with a prepubescent character. But I haven't looked at all of them, nor have I done something more than looking at the screenshots, so if you know better than me, be the grown adult you're supposed to be and use the report button...
If it was true, then MysterTheMan/RetsymTheNam's games would be available here. But it happen that, if some have actually been uploaded,
all have been hit by the rule 1.7 hammer.
They are waiting for you, don't hesitate a single second. Like applications are currently closed, don't forget to specify that your intent is to be the rule 1.7 enforcer and that you engage to play, from starts to stop, all the 20 to 30 games updloaded each day.
