As moderator, I have deleted all those posts where pictures were replaced with exclamation marks. This is most likely because the artists in those posts removed all public viewing of their work.
This also happened to theme pages after the first two years, for what reason I cannot tell.
I have also deleted personal information from members who had left the group before its final year.
Almost all the works made for challenges in the 4 years the group existed are visible in the blog posts themselves. Just keep clicking on older posts to read about the works.
It has been enjoyable to revisit those works this morning, and observe the styles and developments of the artists.
