@blend27 - shall I start listing all ISP ranges from script kiddies, admin.php probes, bogus login attempts ... how about favicon thieves, hot-linking forums?
IMO - This forum is only an asset if it's focused on specific types of threats coming from company ranges that may have negative effects for other webmasters. Reporting some guy on an ISP causing problems on your site is most likely specific to your site alone and not reason to post the entire range of the ISP here at WW.
Nefarious UAs yes, server/colo/data-center ranges yes, new bots yes, because these are the types that affect us all. But as I said above, listing ISPs is not only useless for other webmasters since it is usually a one-time event, but in all probability misleading for those lurking newbies you mention.
@wilderness - thanks for the additional NOC4Hosts ranges. I was missing a couple of those :)
