Clarification on what consitutes "SL" content.

My image got flagged for not being "SL Content" and was removed from the gallery. It was the logo representing the new role we released on our sim. If it's b/c it didn't feature any faces I could maybe understand that but as I view the gallery I have found posters with no sl faces. Can you please explain?

For reference my post: https://www.primfeed.com/abigail.macalroy/posts/7b27abbe-85f9-4f58-a9ee-3d60e6d0b9e5

I have also attached a similar text only image that as of right now is still show in the gallery.
