Another very important challenge would be, how to discriminate those
traffic, due to the CDNs and other geo-dependent complexity.

How to get Alexa top-500 (that we may expect to unlikely be
abuse-generating sites), get their IP addresses/netblocks and route them
over a specific Tor Exit IPs address to measure if:
- They generate abuses
- How much of the Tor Exit traffic they generate

That would be a simple, yet privacy safe, way to evaluate if those
traffic classification and discrimination approach could work in
*uber-simplifying* the life of a Tor Relay operator.
