Sure. "Small" being of course up until, say, 100 posts a day? So you just need to hire a guy that is current on all legislation and court cases related to copyright in all states so he can determine fair use. That's probably not a problem since you'd provide him with a comprehensive database containing all copyrighted material ( audio, text, visual, computer code) and an algorithm that detects legal equivalents of these materials in your forum in real time.
