<Snipped quote by Disdain>

Copyright law allows you to do anything transformative with copyrighted works, so the owners can't stop you. Also, the website probably isn't going to do anything about it.

The website says "please do not" because other, similar sites got taken down for what they're asking you not to do. The site's not demanding; it's pleading.
