Ah, I misunderstood. It will not ask for the address input, if you use /allban nickname then it will ban 3 types of addresses for the nickname you specify.
However, if you have a set list of addresses to ban already, then indeed, you can just use /mode #channel +bbb *!*@*xyz.com *!*@*abc.com *!*@*arnie.com and so forth.
