What's the modern version of something like Counterspy? Covert Action Quarterly seems to be defunct (although they claim to be relaunching in 2018) and something like Wikileaks is too much raw info and not enough informed analysis.
"The publication was targeted by Congress in 1982 with the passage of the Intelligence Identities Protection Act, which made the practice of revealing the name of an undercover officer illegal under U.S. law."
I don't know about this particular situation, but in theory, an agent can be "exposed" through channel that can be not completely trustworthy, so interested parties might not be entirely convicted - and reprinting this information through a magazine printed by ex-agents gives it much more credibility.
