That said, plenty of providers use the list of tor relays (which is also public) to block traffic.

Sites such as https://www.dan.me.uk/dnsbl then help people do this.

That site in particular may "warn":

> This DNS blacklist contains ALL tor nodes (entry, transit and exit nodes) - think carefully before choosing to use this list for blocking purposes.

but anyone who doesn't understand tor simply won't understand the decision and choose ALL.

Running a relay on your own address isn't sensible because of this. Nevermind an exit node.

As someone who has run a relay on my home network for years now this has never come up. At least not that I've been able to discern.

I think it might be a problem if I also ran a mail server from home, but almost nobody does that anymore.

I do, and I've run a Tor relay at home as well (also exit for a while).

Yes, this is a common complaint from relay operators. Running relays at home, or on work networks, is risky.

One way to help that avoids this is to operate a bridge node. Bridge nodes are used as entry points into the Tor network for people in regions where Tor is blocked, so efforts are made to keep the addresses of bridges confidential. Which makes it less likely that people who don't know what they're doing will wrongfully put it on a block list.

One can also run pre-bridges for the snowflake transport by just having some JS code run in a browser's tab (requires WebRTC to be enabled): https://trac.torproject.org/projects/tor/wiki/doc/Snowflake

I had nothing but pain when trying to run an exit node. Every site behind cloudflair would captcha me on what seemed like every page. Cox shut off my internet every other week due to "computers on my network being infected with viruses", and I'd have to call their support and tell them I cant be infected I only run linux at home.

I could do some shenanigans on my modem and end up with a new dynamic IP from cox, but generally within hours that new IP would be on whatever list people use to track exit node IPs and the pain would start all over again.

Tor publishes a list of all exit nodes, anyone could have flagged your new IP as an exit immediately after your client reconnected to the network.
