Only when they do something about it.
Trouble? When they have 40K extra users to pay for bandwidth (easily eats up a T1 or two), it's damage enough. Besides, would you like someone to launch "cyber A-Bombs" (phaa) from your network?
1. Worrying about personal privacy of their users, not wanting to bend too many rules to fight these drones that *appear* like regular users.
Appear? If you own one of the blocks below, please do something about it.
And I know people who mail abuse reports for hundreds of such *lists*, something /rarely/ gets done. One thing they focus on it taking down control web pages. For example if the runner would give a command: 'update http://etc.com/evil.trojan.exe' or if the drones spam themselves on irc.. then it's all about the abuse teams. Some are really responsive, some just ignore. Last time I took the time to inform ISP's about such a list was when it was a 700 large army of *nix boxes. Haven't seen one of those for years before that. It was 3 months ago or so. It was rather funny really. Lesson learned: don't use hostnames like "securebox" or "secureserver1" or such.

{snip} I try and take care personally of drones and abusers I see coming from Israel.. it's way too much work and annoyance as it is, thanks though. Most ISP's truly don't want this as their own problem. I personally don't blame them. Luckily the ISP I work for has no home users. If you have any problem in Israel, whether with finding a contact or reaching law enforcement - feel free to email me and I'd be glad to find you a contact. Gadi.
