I just asked the operator of the "DAN TOR" blocklists to make it easier for people to use the exit-only blocklist, and link to the relevant Tor FAQs so they can make an informed decision.

I'll let you know if he responds.

It appears that they are doing this by mistake, because they are confusing the .tor.dan.me.uk and .torexit.dan.me.uk blocklists (or don't know which one to choose).

Explain that using the .tor.dan.me.uk blocklist will block Tor nodes that don't allow outbound connections (non-Exit nodes), and that there is typically no reason to do this, and direct users to the .torexit.dan.me.uk blocklist instead. (The current "think carefully" doesn't provide enough information for people to make an informed decision, particularly if they aren't familiar with Tor.)
