As to the idea of a VALID_PROXY_SERVERS variable, it makes sense -- *if*
you've gone through as an admin and defined that variable. The problem
is, for people who are just letting Oinkmaster grab new rules without
touching their conf, this rule would break Snort, since they wouldn't
have that variable defined. That said, though, it's a good way to cut
down false positives if you take the time to define the variable, so
I'll add your suggestion to the doc.

That's exactly what the -U flag in Oinkmaster is there for, i.e. merge new 
variables into your local snort.conf so Snort doesn't break when there are 
new variables introduced in the downloaded rules.
I'm not sure anyone is actually using it, but it's there :)
