I debated just attaching to one of the many open threads on this but decided - HEY, THEY ALL STARTED ONE, I SHOULD TOO. Seriously though, I wanted to make sure it didn't get lost.
Recently we closed a thread that had been open for years. There was always an unwritten caution on that thread indicating the pictures inside it may not be appropriate. I understood that and a handful of the moderators understood that. I stopped viewing it and I know others did as well. We have a system whereby items can be reported and it was used plenty for that thread. That's how we chose to deal with it then, again unwritten or discussed. Now, after getting a PM from someone on the site asking us to revisit the appropriate nature of the thread in whole, we discussed it. Those that got a chance a vote agreed that its time should probably be over and that it had degraded if it didn't start that way initially anyway. If anything is true, we know there is no one line when it comes to what is appropriate or inappropriate when we talk about each of us as an individual.
