eerm... this is not mend as avoiding a ban
it just that maybe his nickname contains an illegal character or so-ever
when a OP sets a ban on some-one, it should be done by the adress, so then you isn't avoiding anything
my thought that the topic-starter wasn't banned for his bad behavior or some.... if so then i wan't to say to the topic-starter: "you can't, just be a good boy(girl) to not get banned"
