In your example a user would only have to match one in order to NOT get banned.
However, if you want to include many nicks or addresses it would be easier to tokenize them in a varialbe or text file line. For example set the nicks to %nicks nick1,nick2,nick3,nick4,nick5
Then you can use if !$istok(%nicks,$nick,44) { do stuff } and the same idea for addresses.
