Feral, Pokemon, Digimon, ect. The cub ban does not apply to these characters due to the fact that they are considered beast and there is no true way to say "HEY THAT CHARACTER IS UNDERAGED." That is the long and the short on that.
Honestly if a character looks like a child their whole life? Then whoever wants to draw that character is out of luck. It's the LOOK of characters we are judging by. If something looks like a kid to us even though they are 50 (See Shippo from inuyasha) Then they are still a kid to all eyes involved.
Pokemon are all beasts/feral, Sonic is not. Sonic is anthro. That's really how neer views things.
Digimon, however, are sentient and talk and many walk as 'human-like' as the Sonic crew. If you know the series well, you could argue that they are still 'battle monsters', but I doubt any rep from a payment processing agency etc is going to know that. Surely they will see no visual difference between a child-like bi-pedal sentient-seeming Digimon (or certain Pokémon, for that matter, given how many artists show human-like Pokés as fully sentient AND talking 'human', without changing their appearance) and a Sonic character.
Pinkuh: Also got a couple people wanting to know why Digimon is concidered beast instead of anthro cause they talk and suchDragoneer: They're not child and have no relative age.Dragoneer: not children
That's really how neer views things. I hope he comes by this thread too, but work has him slammed at the moment @_@ You may have better luck posting in his journal about your question if you want him to answer it himself.
