I really don't see why people are taking so much offense over this discussion.
Personally, I use RFF a whole lot at work, and for work. It's an awkward thing to even have some of the aforementioned images display at any point while on this site. I understand not censoring, but allowing for users to determine their content appropriately should not even be an issue, much less a grounds for argument.
We have the ability to place mature content filters in for situations like work and at home with the family, but that doesn't always work for the lazy uploader who forgot to indicate that their image is for mature audiences. I'm not always down to see some guy's Suicide Girls fantasy shot worked out through Model Mayhem and really poor skills. I'm not opposed to artistic nudes, and I am happy to let other poor souls gaze at them all day long. But, I would appreciate a real cohesive approach for those of use who use the appropriate filters and still see the odd one slip in. There is some great photography on this site, I don't want to avoid it entirely because of a select few images, and I think that's what started this thread.
It seems like an easy fix for this is for those who don't want to see that content at times is to indicate that option in their profile, and for those uploading to have some common decency and indicate their image accordingly. For those that don't properly flag their images, there should be a "Flag this as Mature" button or something of the like in the gallery, so that it can be reviewed by a mod if someone finds issue with it's placement.
Just my two cents. Interesting convo, especially with all the inflammatory words being tossed about carelessly by users without consideration for their usage or effect. Oh the joys of RFF.
