I'd imagine that people disappearing isn't an uncommon thing around these parts of the Internet, but that's possible.
I'm afraid that I can't state even his initials without feeling like I'm telling too much... but if you post some identifier(s) of the person(s) you're thinking of, I'll probably be fine with saying whether I might know them or not. Initials or names would be better than actual monikers (which are often much more unique), to keep things vague.
