What points? Can you enlighten me (with an answer please, not with points or a ban

)? I have no idea how it works. And that's why this hole banning thing seems to me arbitrary...
And on what does the duration of a ban depend? Do you, as a
mod, have the powers to ban users and fix a duration on your own or do you have to discuss all this shit with other mod's?
If all those things are written somewhere (regulations ore something) you can give me the link, of course, otherwise I'd be thankful for an answer.
Sincerly
