I dont see how. You mean those 1) covert accounts will be used to
generate false reports?
A reputation scheme reacting to submissions from responders vetted by
account duration is open to legitimate messages being blocked. The goal
might be retaliation of some sort or to cause the reputation scheme to
be dropped.
Or 2) will they not be detectable as spammers because they look like
normal users?
Yes, until they go rogue and submit reports based upon dubious content.
For 1: users who file false reports can have their accounts
suspended/cancelled.
Accounts are essentially free and unlimited. Any reaction to spoofed
submissions quickly degrades into a popularity contest where only those
white-listed are safe.
For 2: its not possible to not be detected as a spammer. Anyone can
be reported as a spammer. The evidence (offending messages) will be
gathered.
Your scheme would not use the community to identify spammers when
content must confirm assertions. In your scheme, how will the service
confirm the source of the message? And what prevents an endless
acquisition of new accounts?
People who have been wrongly reported can appeal.
What level of support staff is needed to review content and to deal with
appeals? Spammers have an incentive to lie, and they often do.
The underlying problem is a lack of a clearing house able to recognize
synonymous identities and a lack of federated credentials when dealing
with "free" identities. Forums are expected to endure some level of
abuse from individuals, weighed against the suppression of speech by
oppressive authorities. Often an abuse problem can be solved by
requiring fees to join, which overcome the economics of spamming.
