I am the operator of exit relays in Iceland, England and Czech republic (as well as some non-exit relays where the providers are less friendly to Tor/don’t understand Tor). The nodes have been built in the last six months (financial circumstance only permitted me to start contributing recently), and I hope to run them for many years to come. As such they are all Debian Linux based with administration via Chef, so I probably spend an hour per month on the admin for all of them in total.

Abuse complaints generally come in the form of automated email from Webiron and similar services, via the hosting providers. In one case, the hosting provider is happy to change the PTR record and abuse email in the WHOIS to an address that I control, so that they don’t bother forwarding the mail. I get about 5 of these per month for all of the exits, and no action is necessary. In rare cases, the hosting company based in the Czech republic asks me what steps I have taken in response to the abuse report. In this case I respond quickly with a polite message with the actions I’ve taken (blocking the host in the firewall, temporarily restricting the port in question or agreeing with the complainant that they will block the host). I spend about an hour per month on this task as well. The most frustrating part of this is when one of the exit nodes attacks a honeypot or connects to a sinkholed DNS domain, and I have to query the NIDS to make sure it is legit Tor traffic and my boxe
 s aren’t compromised. 

The other category of abuse is far more rare but takes a lot of time, and that is legal threat from a company or state entity. I’ve been very lucky and so far only had two such cases, both of which required multiple emails to be sent and staff to be educated in the purpose and functionality of Tor to make the issue go away. These cases took a few hours of work and worrying each. 

All of my exits have a web page on port 80 explaining that they are a Tor exit and what that means. 

Hope this is helpful.
