In the FAQ it says:
When you see bad behavior, don’t reply. It encourages the bad behavior by acknowledging it, consumes your energy, and wastes everyone’s time. Just flag it. If enough flags accrue, action will be taken, either automatically or by moderator intervention.
But how do I flag a post, actually?
(I wanted to flag a spam post here: "No teams are available to join", how do I create one?)
