i think this is a application-logic-thing which can't be implemented that
easy only by one iptables-line

this rule blocks (afaik) every request after the 10th/second, no matter
s.o logged off or on ...
i think what u want must be done on application-level
or with an "magic) (and dirty) script which watches the ftp-log if s.o
loggs off, grep's it's ip and then blocks it for 10 seconds
but that not only sounds ugly :)
