JaeRawrs Well, that doesn't have to mean the work is stolen, though. I, for example, also post my stories on wattpad and I've seen a few other authors there who also post on both sites. So, unfortunately, as a reader, you can never be sure if something is stolen or not
And in that case I'd just report the guy. Though, webnovel can only take the story down if the original author files a DMCA claim against it
