Actually a bush era law got overturned for being unconstitutional, and then reissued again with slightly different wording, but has only been used once (In a case where a man also had real porn to take on a longer prison stay) It specifically mentions lolicon style stuff (drawn works, etc). It was based off the assumption by some parties that porn, drawn, real or fake, of underaged minors could be used by people to "condition" minors into thinking the acts were okay, and thus make them sex workers, slaves, etc whatever. Basically fear mongers trying to use a "plausible" sounding thing that never happens enough to matter to take out a wide berth of things they disliked. Technically every film, book, or art that has an underaged person having sex counted. So every horror movie yah ever watched with an 21 year old doing a topless scene as a "16 year old" was illegal under this law. And its still on the laws.

When it came out basically alot of us artists that had only done lolicon loosely decided to stop (for me it wasn't too much of an issue, as for all intents and purposes, that was "gwen tennyson" and I had been drawing my digimon girls older) as well as specific sites started cracking down (not rule 34 having had a long standing toddlerkon ban, the current loli level is more their providers giving them shit.)

Now I really don't see too much of a reason to draw lolicon, as the few "triggers" i like lolicon for (large insertion, striped socks) are all easily transplant-able, and the few things lost were minor. Petite of age girls are fine, and for the most part much of the loli stuff out there is way to young by my standards as the few I liked tend to be "character of advance mental capacities or character for that age" aka gwen, jade chan, ed from bebop, so on. Think only thing I really missed lately was being able to have the "young guys taking advantage of an older girl" scenario with trades with writers. there are also ALOT of reasons I hate specific lolicons (as shown by the way I get annoyed when people request freak'in mini-moon.)

Either way for me personally I see lolicon as too much of a risk as my art style involves way to many high level things like guro in it, that I want to risk someone deciding he "drew a young girl, and look at all the guro he;s gonna eat one!" or some stupid shizzle that crazy people seem to think when they view artwork and try and turn me into police for absolutely nothing. Cause even if its legal, damn well it'd be hard to find a job after the newspapers drag you thru the mud for being arrested without cause for your "guro lolicon porn!!!"

So sticking to least plausible over ages :P like my april's and so on or the above versions of splatoon girls ^ or gaz's <
