As a private individual, after just receiving my 4th abuse complaint in as many days it's time to stop running my exit node. Prior to today I'd receive on average 1-2 complaints a month (I had a fairly strict exit policy). It saddens me that I have to shut it down, especially as it's one of very few running on BSD, but I just don't have the time to constantly respond to abuse complaints to ensure I don't get shut down by the upstream provider. If there are any devs on this list, some kind of mechanism to detect and block abuse traffic on exit would go a long way to ensuring legitimate use of the network, that is after all why people run exit nodes. It's at least why I did.
Thank you to everyone else running an exit node. I hope you're able to keep yours going for a lot longer than I.
