Forums Scripts & Popups please help in anti offensive nicknames

It seems that it fails in some methods of adding when I add * .sex, it throws an error and bans all those who enter the channel, it could be extended to the code recognizing or accepting special methods such as for example:

/auser 4 *_cam or /auser 4 * _cam*

that can be added with the variants in *
example: /auser 4 sex0*?* /auser 4 sex*!*@* /auser 4 sex!*@*

Thanks for the help
