User blog comment:IWM/OC and Persona: What's the Difference?/@comment-24490414-20160109033426

I think it just comes down to how each person interprets what can be considered a persona or OC. And a  lot of us don't have personas according to what you described so we've been using "OC" as the term is more familiar to us. After all, personas or OCs, they're all simply creations made to fit into the RWBYverse.
