i got a little bug in ZS. Every time a player wants to be /afk, there is the following message: "-Player- is AFK [Removed]" And after 4 times the player will be kicked.
Theres identical bad word lists on lava and zombie, but this "Removed Bug" is only on the zombie server. In the list isn't any word which contains "afk". You just have to type "/afk" to get the removed message. So the list can't be the reason...
It should be fixed in the version 9.8.2. It seems that you got some empty entry in the bad word list that caused the problem. The software now filters out empty entries in this list.
