the mods do solicit CWs from player on their app and there are a few other ways that players are encouraged to list their CWs regularly. CWs are usually a big deal in this game and everyone is upfront about them including the mods

that's why it was so out of left field to have a pregnancy related plot come up without appropriate CWs. a number of players (a mod included iirc) are vocal about pregnancy being a hard no for them. it wasn't a case of the mods being caught off guard.
