Notice: kbin's reached the point all tech reaches where pics of naked people (and artistic renditions of naked people) are beginning to show up -- especially as federation is now up and running. And they should! Bodies are beautiful.
BUUUUUUUUT if you are sensitive to it or browse at work, kindly remember to 1. hover over your username in the top-right ... 2. go to Settings ... 3. and under General/Appearance choose "Hide adult content" ... in order to prevent a good amount of this from showing on your homepage.
I say "a good amount" because it is early days and some content creators are either forgetting to or maliciously choose not to select "NSFW" when submitting. Protect yourself. And yes, if you see any content that is absolutely unacceptable, report it (in the "more" menu on a post).
