You have good reason to be afraid too. Remember the Weev case (like him or not) set things in motion.
What would likely be best is contacting the owners (of possible). Have a 90 day period where you aren't listed but alerted privately. Then if noncompliance is maintained you to public.
Too often though it is hard to determine who to contact - e.g. you have a random IP, you look it up in whois and you find it belongs to a cable-provider.
You can't map to that to an individual, unless you mail "abuse@isp" and hope they pass along the message.
The alternative is to download all the private data, looking for email addresses and hoping for the best - i.e. They don't send a mail to "abuse@fbi.gov" about a hacker stealing their data and similar.
