Your quoted code will kick the person, but won't set a ban.
If you're seeing a ban being set (as you show with the time stamped entry), then that's a different code.
You're going to have to figure out which code (or part of code) is actually setting the ban, and show us that, before we can help any further.
oops, that what stupid, I did edit a line in it
:
if ($eval($+(%,flood.,$cid,$chan,$wildsite),2) == %messages) ban $chan $nick 4Die Flooder!.
