[tor-relays] Bots, love 'em or hate 'em?

My relay says it receives about 50k v1/v2/v3 connections each day to the 60k v4 connections that come in.

"Entry-ips" says it has about 35k guard- clients. Blutmagie says there are no pre-0.2.4 relays talking anything other than v4.

So I'm left thinking that 95% or more of the bandwidth consumption and client count is from crusty old botnet bots running ancient versions of the Tor daemon.

But all that bot traffic creates a lot of statistical "background noise," and so may be providing a service in making it more difficult for advanced adversaries to perform traffic correlation analysis.

Thoughts anyone?
