[Remops] Data on remailer traffic

[cteller at riseup.net]

I'm interested in knowing if there's data on how much traffic goes through
remailers?

I know that's a tricky question. A lot of traffic is encrypted and so you
can't possibly know what it is.

So I suppose what I'm asking is: for exit remailers, how much traffic goes
through? What percentage is (or looks to be) spam or pinger data, and how
much goes elsewhere?

I'm guessing this doesn't exist. I think it would be interesting if it
did. Are any remops interested in discussing how we could put this
together?
