Right now Extension:TorBlock just universally blocks all exit nodes from editing. However, there are some nodes that do not allow web traffic over them, effectively making it not an exit node for the purposes of the wiki. The exit policy can be obtained via Onionoo, so it just needs to be parsed and checked if it includes given ports.
Its also possible to block Wikimedia's servers specifically via exit policies. So this should also be checked for.
