Different usernames don't always mean someone has something to hide
I have a couple of different u/n's. When I first started joining private sites I always used the same one but at some point I joined a site which had broken away from another and wanted to be incognito so used another id. I then got into the habit of alternating between the two when signing up to places, usually using the more personal one on close-knit sites and the other on larger ones or more random signups. I've used a third once or twice on a whim but that's very rare.
I don't see any problem with that, I don't really care about some online identity thing and its never been relevant to my behaviour.
