The false positive rates are only a problem if the admin stupid
enough to consider a single report as definitive. If you deliver a
message to 100 users, and three report it as spam, then you probably
take no action. If 20 report it as spam, then you need to take a
closer look.
Typical results from known spam (e.g. make penis fast) are that about
1% of users report it.
That must depend a lot on the interface that they have. With the mail
client I have currently, there's no way to know how to report spam. If the
client had a "report as spam" button, then I'll bet the reporting rate
would go up.
I get a much lower than 1% reporting rate, except when it comes to spear
phishing, where the rate is a bit better than 1%, even though people have
to find out how to do the reporting.
Also, about 90% of the reports I get include minimal headers, so they're
not very useful.
