Is there a way to report people who decide to cuss at your for 10 minutes because they lost or do I just laugh at them and move on with my life?
*edit, I also ran into a guy who used a entertainment, Truant Durant to pretty much cause the battle to take forever. Is that allowed?
Just to point something out, if you do /ignore the person, your ignore will be erased when you next log in, so if they continue to harass you then you should definitely PM a global driver with screenshots.
As for entrainment truant durant, that doesn't violate EB clause because the point of the strategy is to get up to +6 and then sweep, as opposed to the funbro strategy which was intended not to win but to make the battle go on forever until the opponent decides to forfeit. If he was intentionally time stalling, for example taking a minute or longer between moves even though all he had to do was click protect, boost, protect, boost, etc., then that is against the rules and he can get kicked from the battle for doing that.
