Mods are accountable just as members are. All posts are reportable and if there's a real issue which isn't sorted among us, veve or then even Hilary can decide appropriate action.
I personally think there'd be issues no matter whether we post as ourselves or not. Previously there's been posts where people have said mods are out of touch so we post a bit more. Now its being suggested we mod anonymously which I think would have people feeling like there's no accountability.
I don't know some days it doesn't matter what you do. Bottom line is report a post if you have an issue, that way its seen by all the mods, yes mods posts get reported at times, not sure if any mods posts were reported yesterday though.
