That's kind of vague to say it's "unlikely to see 1 abuser". What is the probability that more IPs in the same /24 are likely to harbor abusers, given that you have received abuse from one IP? And how have you discovered this? ( What is the criteria used to determine that it is unlikely, and what is your source of the information?) Are you assuming that if you've seen the abuse, that you probably weren't the first victim, that the ISP has probably already been notified by someone else, that they have likely had a reasonable amount of time to put a stop to the abuse, and that they failed to do so? There is the one good case where a single abuser has a dynamic IP address; but it's not a safe assumption that they will live in the same /24 next time the abuser dials in. So not only does listing an entire /24 list innocent users' IP addresses, it also does not necessarily effectively list the one abuser. -- -JH
