Safe harbor absolves Kickstarter and Indiegogo from having to uncover the copyright status of content on their platforms. But once they cross the line into knowingly interacting with individual projects, become more hands on, then their safe harbor

Certainly by courting Axanar, both crowdfunders had reason to know of Peters' infringing activity; would they have tried so hard to recruit him without having read his campaign pages, both of which explicitly stated
Axanar was unlicensed?
