What if there was a game mode were your goal was to actually pollute the planet as much as possible?
To be fair, any admin who banned you for polluting would be a boring admin. The game's challenge comes almost exclusively from mitigating that shit with laws and sound governance.
That depends on if you just put your 'sh*t' everywhere to annoy other people or if the pollution is just created by playing the game. The type the 'boring' admins ban are the first. Rightfully so, imo.
