> keep in mind that relay IPs, and perhaps even subnets, may show up on various blacklists

Have you got an example of that? I know a few relays intimately and I've never seen this.

I recall seeing this on tor-talk or tor-relays within the past year or so. Someone started running an exit, and their hosting provider nuked their account, claiming that other customers were being affected by bans. I'll see if I can find it.

Edit: Here's one example, posted by Zack Weinberg on the tor-relays list.[0]

    CMU network operations has decided to move the Tor exit node that my
    group operates (tor-exit.cylab.cmu.edu) to an isolated subnet in order
    to minimize consequences for the rest of the campus network. For
    instance, apparently there have been several cases where third parties
    blacklisted the entire CMU IP space in response to malicious traffic
    from the exit node.  This is currently scheduled to happen Tuesday (Nov.
    4). The new IP address will be 204.194.29.4.

Note that a tor exit node is quite different from a relay.

It is quite expected if you run an exit node. However this was in regard to a relay node, which is something else entirely.

I've seen a few references to these supposed problems with running a relay nodes lately, but the poster never replies with any information where this have actually happened. This behaviour is new. It wouldn't surprise me if it's coordinated, considering what else we've seen lately.

It happened to me when I ran a tor relay (not an exit) on the same ip as a mailserver. There is one rbl that automatically adds you if you do this. Mind you, I've never found a mailprovider using this list (can't remember the name).

Can you see if you can find the RBL in question? Since there are a _lot_ of relays around the world, surely someone else must have noticed?

Numerous sites pull down lists of exits daily/hourly/$xly and retroactively block them, although I've never heard of a subnet being blocked.
