The amazing photographer photoport (Pavel Kiselev) has been banned permanently from deviantART.

DA's response to an inquiry was:

"Thanks for your inquiry. We cannot discuss the reasons behind another users ban with anyone but the actual user."

He was a member for 8 years, a current premium member, and had over three MILLION pageviews. This was not some hack; he is clearly a professional.

You can see some of his work here: [link]
You can buy his books here: [link]

You could be next.

Update (3/17/2012):

I purchased his Railway novel from Blurb (in softcover). It arrived, and looks to be good-quality printing. I love his B&W window light shots.
