How about "rumor"/"insider" posts be relegated to just "My friends" only status...?
If random, outsider musings happen on CB, they shouldn't see anything that exposes athletes, unless they're friends w/ someone that does post this stuff. This will put an emphasis on what friends, CB users decide to take on.
If there's a public rumor posted, moderators just change the status to friends only...
Seems like a reasonable step to minimizing any public blow-back...
