As someone involved heavily in IRC and the running of several IRC networks, I think the primary reason most networks use random blacklists for tor (there are several, some better than others in terms of operating properly) is the unusual format of the official dnsel (
https://www.torproject.org/tordnsel/). Notably, with the software most people use for proxy scanning, getting the exact port used to connect is difficult or impossible, and sometimes the server IP is as well.
It might be beneficial to provide the DNSEL in a standard format (without the destination ip/port) as well, for situations where that distinction isn't feasible. This would at least be better than leaving that blacklisting to third parties who often don't understand quite what they're doing :P

I've gotten on some DNSBL list, which basically keeps me off of several
IRC networks. The catch is: I'm running a middleman-only node!
I really hate how some of those blocklist maintainers indiscriminately
add the entire contents of the Tor directory to their proxy lists. It'd
be really nice if they used the exit-only list that is put out
specifically for that purpose...
