I don't like censoring but certain places require it for the site to grow. Even if just kept to a minimum.
If you are aiming for a certain audience only, by all means, go uncensored but if you are trying to bring in diversity, you either need to have a site that is already well built or keep it PG-13 for a while until people become comfortable, otherwise they'll split and you'll stay with the original members.
Kind of boring to have just one type of person... especially if it is all people you know IRL. Why not just make a chat board as opposed to a forum?
If that makes sense... I'm sorta drugged up right now. ;P
