I dunno about other people, but I usually check a dictionary if I don't recognise a word. And as you might expect, "concrit" doesn't show up in a dictionary or any reliable websites, so one would assume it's a typo.
Edit: fanlore.org doesn't sound like a go-to site for looking up words you don't know, so I'm not surprised that people would overlook it.
