Confusion amongst the boards

Okay, I received three "Your Content Has Been Removed" messages. I originally posted my art in the correct place under "Skin and Champion Concepts" but I received this message...

"This content was posted in the wrong board. We'd like to encourage you to repost this in the "Champs and Gameplay" boards. Also, please take some time to review the Guidelines for each board before posting. These can be found in each board on the bottom left-hand side of your screen."

So I reposted it in "Champs and Gameplay" and received another "Your Content Has Been Removed" message. This time it said...

"This content was posted in the wrong board. We'd like to encourage you to repost this in the "Skin and Champion Concepts" boards. Also, please take some time to review the Guidelines for each board before posting. These can be found in each board on the bottom left-hand side of your screen."

So the boards are confused and so am I on where to post my art and participate. Very frustrating. Please explain.
