I give it maybe 2 years... There will be a briefing on security clearances, followed by an in-brief into various programs. One of the admonishments will be a requirement to report every inquiry about certain topics, especially if they are pointed and/or repeated.
Less than 6 months later, some "enthusiast" will ask 2-3 pointed and repeated questions about something specific, and *poof* serenity will quit frequenting various online forums because its too much hassle and not worth risking the clearance.
Until then though, its fun talking about it. But trust me, there will come a point where it just isn't worth the hassle trying to remain on the correct side of the line while discussing the job.
18ish years ago, a guy with an Israeli online handle and persona got pointed with some questions on an F-15E forum, and I quit even reading fighter enthusiast forums. One kid built an entire online persona based on asking several members of my squadron a couple questions each, to the point where he claimed to be on a specific deployment and started putting names to faces in squadron deployment photos that had been put on an open server. OSI got to deal with that one. I learned some time later that I probably got investigated myself over Janes F-15 content, although nobody ever interviewed me about it.
Then 20 yrs later after the last read-out, it'll be ok to talk about the job you used to have because while you'll still have to answer "what what I dunno what you're talking about what what?", at least it won't be reportable.
