Yesterday, I may have pulled the trigger too soon when I deleted all images that depicted children.
It was a classic "manic Monday;" I was busy as a one-armed hairdresser, did not have time to research the matter, and took the safe way out by pulling the plug as fast as possible on those images to avoid being accused of disseminating "k1dd1e p0rn."
Tuesday is vacation-like compared to Monday and I had some time to do some research this morning. I found the applicable federal law, US Code Title 18, §2256, which defines "ch1ld p0rn0graphy." See it for yourself here, specifically paragraph (8).
I am not a lawyer, although I did portray one in law school, so my interpretation may not be correct, but it seems to me that the images I created and displayed here did not fall under the US Code definition of "ch1ld p0rn0graphy."
I doubt that this will change my decision about deleting the images and not posting similar images in the future because it is not worth the hassle if someone wants to make an issue of it.
