bigbitmine and El Emperador's avatars are fine IMO.
I think this statement ends our discussion about avatars for now, as they are fine!

After putting some more thought into it, BadBears comparisson with ads ended the argument for me.
I wouldn't consider clothed girls NSFW, I see worse than that all the time in ads. Probably shouldn't be browsing the internet at all if that will get you in trouble. Though historically, theymos and I have somewhat disagreed with regards to NSFW content in the past, so don't take that as a final answer.
It does say a lot about the user though, so there's that.
I don't see why an ignore avatar function couldn't be included along with ignore signatures if/when it's added.
Kinda miss the old Avatar though.
