You are not allowed to submit wallpapers you did not make, continue to do so and you will be banned.

MT Policy
Just like Ayamael stated, you are not allowed to post wallpapers you yourself did not make. I suggest you delete your entire gallery.

Hi! I see that you are new here, and you mustn't have read the support section, because all the walls you submitted so far were not made by you (they're either official or made by someone else), which is against MT's rule. You are only allowed to submit artwork you made yourself. I suggest you delete all the walls you submitted immediately or you risk getting a warning.

Go read this : http://support.minitokyo.net before you get a warning. Mainly the policy and the FAQ sections : http://support.minitokyo.net/policy/ and http://support.minitokyo.net/faq/

Otherwise, welcome to MT.
