Anime bondage may reflect poor taste, but it is not porn.
Depicting child porn, even cartoon-style, is illegal in the US.

The artist claims he never draws nudes or furries. Furry porn is not unlawful so long as all the animals are over 18 and have given their consent. Otherwise they should have the stuffing beat out of them.

I prefer to keep within my species (though I once saw a hot looking Vulcan...)
Makes me wonder what Klingons would consider kinky.
