You seem to be seeing it only as "a single ordinary user making site-wide decisions on what to block" versus "totally ignoring what the users say" choice.

If that binary choice was the only choice, I'd agree with you. I have enough horror stories of goofs in that regard. Hell, I have enough horror stories when the alleged expert (me) screws up good.

But that is _not_ the choice. Acting as if it is is at least mistaken. TiS buttons aren't implemented that way.

_Nobody_ is talking about individual ordinary users making site-wide decisions of what to block. That requires very high levels of expertise as you say. But there is absolutely nothing whatsoever wrong with taking note of what those individual users are saying, and using it in a statistical fashion to guide your filtering. That is how TiS buttons are used in infrastructures large enough to bother with them. It is, after all, how Spamcop was originally implemented, and it's still part of their decisioning process albeit less than it used to be.

There are non-user-driven DNSBLs less useful than Spamcop ;-)

If we were to specify/standardize/or even (gasp) implement a common TiS strategy/implementation that actually drives filters, the crucial part is coming up with a "filter decisioning" strategy that the admins can tune, and has reasonable defaults.
One trend making eradication of spam fairly difficult is when large ISPs have customer's accounts compromised by the tens of thousands. This problem can elude statistical analysis, as you suggest. Often less than a dozen emails that appear to be fairly real are sent from any particular account. These compromised accounts might be used to commit other nefarious acts beyond spamming, such as deceiving friends in the address book that the holder of the account is stuck in a third-world airport with their credit-cards and tickets stolen, and is requesting a wire-transfer.

Being able to employ end user feedback indicating unwanted input might be of greater benefit as a warning for compromised account holders, than as a method of eradicating spam or for tuning filters, due to a potential for creating false positives. False positive filtering trained by user's feedback can happen when someone forwards email from one account to another. While this type of feedback can help identify spam missed by content filters, spammers have become better at creating content nearly indistinguishable from normal chatter.

Developing practices better at securing customer accounts are needed, in addition to offering account holders warnings that their email account appears compromised, which might mean imposing some type of security hold on the account. While this could be costly from the aspect of customer support, providers need to accept a fiduciary obligation at keeping accounts secure, which is to monitor and report evidence of abusive activity. This monitoring should include tracking end-user feedback, as well as finding methods to block break in attempts.
