This seems to me like copyright issues or, worse, image rights.
I don’t know about LC, because I haven’t had time to fully explore the site yet, but on ATF there were many animations involving scanned models, which must cause a lot of problems. Characters like Sarah would probably result in heavy copyright claims, but that might be worked around. However, characters like Laura (Silent Hill remake), Sherry (Resident Evil), and some others would likely cause a massive legal issue, since they are 1:1 scans of real children, not sculptures. I might be wrong, but that would be my guess.
