Default Relay Exit Policy
There are two opposite points of view as to what should be the default setting for running a Relay: Either no exits should be allowed (a no-exit Relay) or all the exits should be allowed.
Less than half of all Relays are exit Relays considerably diminishing Tor's capabilities. So setting the default Relay configuration to no-exit would be counter-productive to Tor's purpose. On the other hand, permitting all exits does expose Relay operators to increased risk. It appears then a compromise of setting the default Relay configuration to exits for unsecure and secure websites would let Relay operators provide a valuable and essential service while at the same time reducing the risk to themselves.
