The chat filter in its current state is pretty ok it can filter out bad words and it blocks every kind of link (even from this forum). One thing its not capabale to do is to limit spam. Currently people can spam whatever they want. The only way to get kicked for spamming is if you write the same thing (even commands) about 20 times in 10 seconds. What I suggest is that people can post the same message only once every 12 seconds. This is 2 asc ticks, which should be long enough. When you try to post the same message more often than that it should just be blocked out with a warning like links right now. If you really try to spam this message regardless There should be a small chat mute or a kick (to prevent spam bots). I just suggest this because this server has a rule which states: #6.1: Spamming a specific message/multiple messages is not allowed. We are low on staff and this rule used to include double posting until Wazez had the genuis idea to tell some players that double posting is fine otherwise the bot would pick up on it. It's useless to /report because we are pretty low on staff and its not considered a rule break right now. This would also help player that accidentally post the same message twice in a row. This should exclude all the / commands. Also whitelist player names for the bot. #3.1: Inappropriate / Offensive Minecraft Account names are not allowed. When I can't say the name it most likely breaks this rule anyway.
