Actually, John is spot-on with this one. Comparison of statistics from (a) a fair number of diverse production mail servers and (b) a large-ish number of spamtraps over a period of many years does in fact show that the percentage of spam from Tor nodes asymptotically approaches 100%. (I have never bothered to rigorously analyze it because for my purposes the difference between 98.94% and 99.31% is irrelevant.) This of course is not equivalent to a statement that all of the SMTP traffic from Tor nodes is spam. There is some non-spam. But for all practical purposes, it's lost in the noise floor. But to circle back around to where this started: whatever the percentage is and however it fluctuates, it really doesn't matter to a web site that speaks HTTP(S). ---rsk
