That's a good suggestion, and I was planning on putting something to that effect in the site registration process.
But there are times where it might be okay to copy and paste: Any content that's older than July 2012, via Archive.org is clearly okay. There are some places where we may be able to copy over some data that isn't really subject to copyright. For example, I suspect that a bare list of tropes used in a work does not actually count as a creative work on its own. Or it may be so trivial of a portion of a creative work that it would qualify as a fair use. If you paste a lot of sentences from CC-BY-SA-NC, it's obviously over the line, but copyright law has substantial gray areas. While we can try to minimize infringement, ultimately we'll just have to wait for DMCA takedown notices to come in to see what happens.
I have this sort of perverse fascination with what would actually happen if there was a lawsuit over this. Headline: Website sues forked site for using free data on another site with a slightly different free license which is the license it used to use, for violating the noncommercial clause when it is more obviously noncommercial than the original site. I wonder if they could even possibly show damages? Would I pull a Crazy Ivan and try to get their license invalidated, because they have never asked any users for a license explicitly? That would invalidate our dataset too, but hey, Pyrrhic victory. And even if I got sued and lost, they'd still have to wait in line behind my massive amount of student loans before they ever got paid, because the government always gets its money first. Well, until I actually get around to incorporation, that is.
