thallub, while I've never heard of this, I'll take your word for it.
Even so, it would have been nice if they'd mentioned that in their request for emails on the topic. And they should definitely not publish contact information without express consent. (It would be a violation of Federal policy for them to publish similar information about their own employees; Privacy Act stuff.)
Of course, I don't recommend submitting anything to a public forum (or government agency) that I wouldn't wish to admit to at a later time, so if they were to publish my response, it wouldn't bother me.
