The best advice I can give is not to allow unprotected (i.e. without a
captcha or similar) inband registration, as people use scripts to
autoregister accounts across many servers using IBR. If you require
registration through a web page with captchas etc. then at least a
spammer has to target your server specifically, rather than being able
to use the same techniques across many servers.
