Every time a player sends a message, this message will be tracked and compared
to his last one and if that message is % similar it will be blocked!
similarity-check:
enabled: true
cache-message-seconds: 10 # How many seconds will a message be tracked
threshold: 0.75 # The threshold to flag the check
With /zelchat similar <String1> <String2> you will be able to compare two strings
and tune better your threshold
