What's the story on Avatars and Signatures?

[August]

As I'm scrolling on these threads, on my lunch hour, multiple times today I've had to quickly scroll past people's posts who contain GIFs of inappropriate content.

I know there's no nipple, but a GIF of a woman with large breasts, in a bikini, smashing them together, is not 'Safe for work' for me. Nor is a woman on all 4s shaking her bare ass.

Look, I can set a filter for imgur, and I can use adblock to block these type of ads. But, I have to see them at least once. I guess I can also disable sigs and avatars by default as well.

What's the consensus here? Don't infringe upon our rights to display slightly NSFW avatars/sigs? Should there be some moderation here? I'm at the point where I just have to, you know, actually work while I'm at work instead of browsing forums.

Not intended to be Rants and Flames material. Legitimate concern/question.
