In General, finished with the mod and then comes a random visitor to the server with the nickname and did not react to his greeting. Naturally I decided to check myself and it turned out so that I, too, did not react.
Decided to experiment and it turned out that team !players !admins !and statistics, etc., Mod gives errors with this nickname is such :
