Chat filter

The chat filter is the censor in the RuneScape chat system. The chat filter automatically blocks any words that Jagex deems inappropriate or potentially harmful, including but not limited to:
 * Any swear words or offensive names;
 * Names of websites (i.e. Google) or parts of URLs (www., http://, etc);
 * Words that can be used to ask for personal details (such as e-mail, address, and phone).
 * Key commands which can be used for scamming.
 * In the public chat, if someone types "::" before the body of their text (and don't use effects), the text wont appear in the box or screen. Example: Type in ":: i liekz mudkipz"

The filter automatically replaces any inappropriate words with asterisks. For example, if a player typed the word "password" into the chatbox and pressed Enter, it would come out as ********. ("Password" is blocked because asking for another player's password is against the rules.)

Jagex has said that the filter is in place "to maintain a good playing environment for all players." Abusers of the filter can be reported to Jagex via the Report Abuse button under Rule 1.

Players cannot be reported for filtered messages; in such cases Jagex claims no rule was broken as the chat filter did its job. However, players that manipulate the filter by bypassing it and saying words that are offensive CAN be reported.

Changes to the chat filter are generally classified as hidden updates.

With the long list of words that the filter is programmed to censor, it also commonly censors not offensive words accidentally. One example is that if ", gf" is typed, if will result in "****".

Some players think its unfair that "To school" is censored, Example: ''I couldn't get 85 Mining yesterday, I had to go to school".

In RuneScape Classic, the chat filter would replace the blocked word with the word "Cabbage". An example would be, "You are a cabbage." This was changed since it confused a lot of players.

Trivia
,
 * On January 13 2009, few censored words became uncensored. Examples of them are: "to school", "phone", "address", and some offensive words such as "suck","ass","balls","sucking","crap", "damn", "hoe". There still may be more, but is yet to be found/updated.
 * Jagex Moderators have a censor in-game but do NOT have a censor on the RuneScape Forums, allowing them to say whatever they want!
