With made-up words or foreign concepts, it's natural for our brains to fill in something more familiar when we're typing them. It's Moder not Modor, Draugr not Drowger, longSHIP not longBOAT, etc. And then there's a wide variety of nicknames that are widely understood. Goblins, skeeters, and so on.

Honestly I'm more annoyed when I see "ppl" instead of "people." But that's just me, I'm old and cranky. Now get off my lawn.
