All of the tor exit nodes on campuses with good journal subscriptions have disappeared or they have been marked as open proxies by the journal cabal. I used to be able to get any journal pub via an exit node at BostonU or GaTech.

dx.doi.org needs to disappear too. Two of the three ipv6 endpoints are always down and unbound never seems to shuffle the addresses in such a way I get the working address first:
