RuneScape Rules
Like everything, RuneScape has rules. These are not to make the game harder, or to annoy anyone, they are to protect you. Please, adhere to them at all time - it makes the game better for everyone. The official rules can be viewed here. It's very important that you read them carefully, if you accidentally break one you could be banned from RuneScape

Reporting abuse
If you see someone breaking one of these rules, you ought to report them to Jagex. If everyone reports abusive players, then the game will be a better place for all. You can report abuse by clicking the button in the lower left hand corner of the chat box. You need to type in the player's name and then select which one of the rules they are breaking. This sends a snapshot of the last 60 seconds of chat and trade activity to Jagex. Please, only send in an abuse report if the player is genuinely being abusive, not just because they called you a 'noob.'

Alternatively, if the type of rule breaking would not be detected by a simple chat and trade log (such as the player is macroing) you will need to use the customer support section on the RuneScape main page to report the player.

Player moderators
Player moderators are RuneScape players just like you and me, except Jagex has selected them as being responsible members of the RuneScape community. They are able to temporarily mute players who are being particularly foul-mouthed, and their abuse reports receive additional priority. This does not mean that they can answer all your RuneScape questions or that they always want to buy or sell items. They want to play the game, complete quests and raise their skills just like you do. When a player moderator talks they have a small silver crown next to their name in order that they stand out from other players. You can read more about player moderators in the Frequently Asked Question section on the official RuneScape site.

Jagex staff
Jagex staff have a little Gold crown next to their names when they talk in-game. Follow all their instructions promptly and you will have no cause for worry. If a member of the Jagex staff asks you a question, it would be wise to reply to them. Please note yourself that ignore chat messages will not work on Jagex staff or player mods.
