Ask HN: Tech conference organizers, how hard is your job?

Many of us go to conference to present their work, connect with like-minded individuals and possibly finding the new opportunity.

From the off-hand remarks from some conference organizers, their work carried some risk and could be thankless. They could face the following unpleasant things: * A speaker got cancelled because of something they posted or said. * Nasty people violated code of conduct. * Conference organizers got verbal abuse and death threats because they rejected a speaker's proposal. * Anything money related.

What are the other difficulties of the conference organizers?
