I just bought a pass on craigslist…

PLEASE DO NOT DO THIS!  The chances are good that you’re buying a fake badge or otherwise getting scammed.  We hear stories like this all the time, and it really breaks our hearts.  Unfortunately we have very strict capacity limits, and we control them by the number of badges we print.  If you get stuck with a counterfeit badge, we simply cannot let you in the building regardless of how much you paid.
