If the post were seen by his employers somehow, I assume there are only so many people working on that team. Not to mention the fact that they could search his name for other posts on this board and see, for example, when he posted about getting hired, which gives them a date. And who knows if Aemon has used his first name in response to him somewhere on here (they're in-person friends).

And even were none of that true, it still wouldn't be worth it for random internet strangers. When you love your job, you respect your job.
