I'd say it doesn't affect my traffic at all, but for a month now I have contemplated starting up a proxy site using an unconventional script (Not PHProxy or CGIProxy I mean). I have put it off until Mid-August though as most traffic usually comes from Schools, Colleges etc.
One of my parked pages related to proxy traffic doesn't seem affected either way. I reckon that the traffic is just growing at the same rate of loss from schools traffic and so in September, I'm expecting quite a rise in traffic (And revenue
).
