as one of several mods, this is my take on this.
the N from A thread had become long overdone though. the thread had been up for close to a year, hundreds of replies that consisted of different takes and ideas that would counteract with eachother in a negative way. as @SinisterKid has pointed out, there is just a ton of confusion if a thread that old is up for so long.
with the thread about the drones, threads specifically that included are closed for reasons. for ex, instead of willing to understand and empathize with OP and what he believed he was dealing with, individuals began to question OP, argue with him, and it derailed from trying to empathize and understand OP to questioning if OP was paranoid and interrogating OP and asking for proof because of their own satisfaction.
more than often, threads including the one above are closed as a preventative measure in having it escalate and become worse. the chances of both threads "blossoming" into something productive and positive including the Drone thread was extremely slim. as for the N from A thread, there eventually will be a new thread that's fresher and up to date.
