Problem is, a guest sees all public boards, regardless of her/his age.
the visible image will become part of the general reward of a site.
Normal, that in general chat some loose lingo occurs and is tolerated ...
I don't think all public boards should be public for non-members, thus.
The game-specific boards though could be an attraction as first spot,
unless some obsessive idiots misuse it for cheating their reward. ~*~
