Hi,

you can create an alias (URL table) with a blacklist file. Then you can define Block/reject rules on your interfaces.

I use this list:

I think it would be possible to create that list using tor itself as it has the list in memory. However the tor project provides an API endpoint by itself: https://check.torproject.org/torbulkexitlist

Please no not query it excessively - maybe once a day.
