Nobody is going to prosecute people because of some drawn lolis.
Drawings are all legal.
It can only cause problems if combined with some other crime where your attraction to lolis can be used as evidence.

If you live in the state where certain types of fantasy is a serious crime, it is preferable not to try making money on that.

All this anonymity issue is because of social status because you definitely do not want your relatives and friends to know that you jerk off on mutilated lolis.
But if you draw that as commission you can just say "Hey! I draw whatever I am paid for"
