And it's wrong:
Tor attempts to find the closest exit node to the end point in attempts to speed up service. In most cases, because of this it is possible to curb abuse originating from the same places by blocking outbound traffic from just a few exit nodes.
And their firewall method is unhelpful, as it may get exits the BadExit flag:
There are a few ways exit traffic can be rejected:
• On the exit nodes themselves
• Tor exit itself (see: https://www.torproject.org/docs/tor-manual.html.en re: "ExitPolicy policy,policy,…")
• Local firewall (ie: IPTables/Windows firewall)

They are probably using the wrong list, there are reliable lists
maintained by Tor, as far as I know.

Ask them to join tor-access@ and explain their issues?
