My opponent is cheating/escaping/being annoying!

Be patient with us! The moderator team is run by volunteers and there is not someone present 24/7. Please do not spam the button several times. It will in fact make the reaction time slower for us. If no-one is showing up immediately and you are getting frustrated, just resign the game and play with someone nicer in the meantime. We will get to you eventually, annul the game, and punish the culprit. Do not let one angry guy ruin your day.

You did exactly the right thing by calling a Mod and just resigning. While the available solutions aren’t perfect, they are sufficient to ensure that good experiences vastly outnumber bad ones.
