A recent user on the site has prompted me to start this discussion, so bear with it.
As most of you know, Cardsmith has a policy for explicit art and so on for cards. Some of us choose to ignore it, and face deletion.
This is most likely a repeat of the policy, since I'm kinda lazy to check it now, but here :
1. ) If your art is pretty revealing, provocative, or has lots of nudity or reveals the crotch or women's breasts, forget it.
2. ) Middle fingers and FU's should be avoided.
3. ) Explicit language on a card is almost always a no-no.
4. ) Remember, a lot of adolescents and preteens use the site. Try not to do anything in the first three points.
