Depending on your actions on the forums, and the story you claim, I see that the ban was completely legit. First of all, if a staff member is talking to you about a rule, you should listen to them, and read the rules carefully. Here is the rule referring to this situation:
4.2 Base Appearance - Bases must not have flickering effects, invisible or anything difficult to the eye. Anyone entering the base must be able to see where they are going. No completely blacked out rooms the black material can only be used on one wall.Printer safes do not need a transparency change. Your base should not stop vehicle access on the roads, vehicles should be able to pass with ease. Excluding district bases.
I haven't checked your recent warnings, but if you have more than normal, and adding this situation in the equation, I am gonna stay extremely

for this.
