I was just wondering, why was Yameki banned?

I never knew him, but in a Topic I saw, he edited a Picture of Cloud, so that he had Grey Hair. (I would assume that this is not the reason that he was banned)

I kept on reading the topic, but later in the topic I noticed someone said: "But I wonder why our artistic friend was banned?" (Or something to that effect), and I looked back at the first page, wondering who he was talking about, and I noticed that the creator of the topic was Banned! O_O

This must have happened recently, apparently. Because the Topic was made Recently, and you can't make topics when you are banned. o_o

So, I was just wondering what he did that got him banned. Sorry if this question seems to be very pointless.
