There's an awful lot of cross-domain 302's out there from very important authority sites. I believe that if Google did this, that they would see a huge upheaval in the pagerank distribution across the whole of their SERPs.
For example, it is no secret at all how meaningful Yahoo Directory listings are to the *average* website in terms of getting ranked on their primary keywords. Every link in the Yahoo! Directory uses a 302 redirect.
If google suddenly threw out those links from their PageRank accounting, they would probably shuffle up their index a great deal as a result. Right now they have results that make them a good deal of money and it would be ill-advised, from a shareholder's perspective to just fix this problem and see what happens.
I've said all along that google knows about the problem but that there are larger issues preventing it's repair that it can't disclose.
And I know two other people who sent one. Maybe you should check again? I doubt me and my mates account for 10% of your responses.
If you believe that the people affected by this are all "spammers" then perhaps the problem is false positives for your spam detection filters.
In fact you should probably take a look at your spam detection filters anyway. Last time I checked--probably much more recently than you checked for canonicalpage emails, there was a bunch of scraper sites running AdSense where good relevant results used to be.
