Short, because they are the game's.
Be decent. Vandalism, made-up numbers and insults get the same answer as in the game: staff revert, close, mute or ban. Upload porn, gore or anything that is not this game and you are banned for good - no appeal. Software looks at every picture first; a person decides.
Write what you know. A number you measured, a thing you saw, a story the game told. Say where it comes from in the note.
Never change the current column. It is the server's; the sync overwrites it within the hour. Use the suggested column.
Any language in your text; numbers in English. The tables are read by a program.
Pictures: your own screenshots of this game, nothing else. Every upload is checked by software before it shows; a flagged picture stops your uploading at once and goes to staff. Bad material is a permanent ban without appeal.
No links to other sites in your first day. Afterwards, only where they help the page.
Trolling is punished like in the game. Reverted, closed, muted, banned - by staff, by hand.
Your edits carry your in-game name, and the page history keeps them. Nothing else about you is stored here beyond what the privacy page says.
