no, maple means you cant post a CP set at all.
it all depends on how you make it as to whether or not its illegal. if you do what vermine/aerox do, which is take a random stock, which is like a sci fi scene, then turn it into a character concept, i dont see the issue with it, cus the result bears no resemblance to the stock.
those that take a head and turn it into a head while keeping the same details and then selling it for creds, thats another more delicate matter. we're moving into making profit off other peoples work, then do credits relate to profit outside of RL? etc etc.

iv got no issue with bringing back the "credit the artist" rule, would be happy to enforce that.
but a no CP set rule. not gna gel with me.
