One person seems to have banned just because he couldn't load the engine.
Sorry, but this is an understatement. I should have made it clearer, but it did look like severe idiocy or spite.
First time, he started to ignite the engine when I was loading cannisters. I closed the valve and told him not to do this yet. He opened it. I closed it again and begun to connect other cannisters. Of course, he did exactly the same thing he did earlier. He has been shouted at by the captain. About ten minutes later, he tried to open the engine loading chamber inner airlock, effectively sealing it off (with the storage containing perfectly good cannisters) and dying in a fire.
Next day I joined late, was assigned to the engine and saw the engine running without being loaded. Then I realized it's the same guy as the day before.
I forgot to mention that the entire time he was writing in lower cases, with multiple spelling errors. And he had no first and last name, only something which looked like a nickname.
Our banning may seem somewhat harsh, but it's extremely easy for one person to fuck up the entire turn for everyone. If we begin to give those people second, third, fourth and eleventh chance, we will have no time for playing, because every turn will be destroyed by a moron who can't read the Wiki.
