I'm not sure how relevant this is to running your website on the "darknet", but a potential warning for future Tor service operators: I ran a TOR relay for about a year, eventually even ordering a static IP for 5€/month. One random day, I was unable to log into my online banking, receiving some obscure error code. After digging around and finally contacting the bank, they referred me to some "IP protection service" in the UK, which had put me on a blacklist for unknown reasons (they don't tell you the reason for security reasons, but there was mention of something "proxy"). After submitting multiple requests to remove me from their blacklist (all automated online with no option to talk to a human), I finally caved in and shut down my relay. After doing that, combined with waiting a few days, while also continually resubmitting my removal request, they marked my IP as "clean", allowing me to login to my bank again. The whole process took about 6 weeks, and neither my bank nor the UK service provided any assistance along the way. Fun times.
I would love to run a TOR relay again but I'm a bit paranoid now.
