I'm not for certain, but it seems to me that some Monks magically appear on a thread if a specific topic is mentioned, or perhaps their uid is mentioned.

Can someone explain how this is accomplished (or at least tell me that it isn't happening, and I'm just imagining things)?

I mean, mention threads, and without fail, a major resident expert magically appears. Could be coincidence, but I'm not sure.

Question is, is there a way, without having to continuously re-roll the Perlmonks website scraping, to see if a username or phrase or something is published, to recognize this? I'm definitely no web expert, but I can work my way with JS/jQuery/CSS to a degree, but searching is usually required.
