A lot of your stock photo deviants seemed have changed their rules:
"We want a stock photo account with no strings attached.
+If you submit stocks here to this account, you agree to let the DA members to use this stock image completely free of charge, commercially, or non-commercially, and not require them to report back to you, or credit you, inside or outside DA.
+Members are to use and alter the stocks for creative, educational purposes. Members should not resell, repost the stocks as their original/unaltered form for any reason without permission,
+Crediting the source is not required but appreciated.
+And the stock's copyright has to be owned by you, meaning don't submit stocks you took from other places."
