We've had a lot of these, and we think we've figure out what's going on: HBO's notice is based on detecting a particular address' presence in a cache - basically, a server publishes a list of addresses that will provide the desired content. When HBO sees their content on one of those lists, they grab all the addresses in the list. But the problem is, this is not a live list - it lives on the server for a certain length of time until an inactive address times out. On our wired network, where addresses tend to be re-used by the same device over a long period of time, an HBO complaint based on this tactic usually captures something real. But when it's a wireless address (in our case, through our VPN), we cycle through the address pool fairly quickly. So by the time we get the complaint, a simple time stamp for when HBO saw the cache list no longer gives us enough information to track down the offender. So the problem is not that HBO is giving us bogus information; it's that they're not giving us ENOUGH information. They give us an address that has been used *at some point in the past defined by the caching time*, without giving an indication of when the address was ACTUALLY used. So we can't really find the culprit. And that's basically how we've been replying to them... Meanwhile, we're altering our policies to simply prevent bittorrent, etc. on our wireless/VPN. Legitimate users can use the wired network.

Most have indicated activity more than 9 days and as long as 15 days old. My responses haven't bounced, but I did tell them that chances of finding anything of value from data that old was negligible. I have yet to see anything like a reply to email or returned phone call from any of the senders of these notices--not just from the HBO outfit. I wonder about the validity of these notices ... enough so that I'm tempted to recommend they be added to the spam filter. Guy L.

notices from HBO.
I just reviewed our DMCA complaints. We haven't been bothered by HBO much at all, but just got a complaint recently. It was sent 10 days after the alleged infringement and implicated our proxy server for which we don't keep logs that long. The delivery headers of the complaint didn't look suspicious, and my reply didn't bounce. Bob Utah State University
