That's a fair statistical analysis so I get your point. With respect to Usenet, I'd fully expect that the endpoint logs, but not every intermediatary who happens to have an agreement with another intermediatary, which is the issue with tracking on the web. Distribution of information is no longer controlled by the endpoint or by contract, but rather by coincidence via any nefarious method possible.

If I did something naughty, I'd expect to get caught. This is not about anonymity, but about the assumptions that people draw about you based on unrelated information tracked from multiple sources.

However, I'd rather be an obvious objector than annoyed by donkey porn adverts :)

I don't see ads either (Firefox+Adblock+ghostery+noscript).
