binlog_ignore_db keep replicating mysql user

Hi,

We already set the options below in our .cnf file

[mariadb]
binlog-ignore-db=mysql
binlog-ignore-db=information_schema
binlog-ignore-db=performance_schema
replicate_ignore_db=mysql
replicate_ignore_db=information_schema
replicate_ignore_db=performance_schema

but it keeps writing create user in the bin log, thus the user keeps being replicated in the slave.

CREATE USER `cehau37_Copy1`@`193.1.1.2`
/!/;
