I think that everything you said should apply everywhere; as someone who got chat banned once, I am sure things happen. You can lose your cool and say something you shouldn’t have, but you should always try your best not to have a slip of the tongue and if you do, well the best thing you can do is to apologize to the person if you can, or at least try to make things right even if they don’t accept your apology at least you tried. (I may have worded things a bit weird sorry, not the best with words sometimes)
More true words can’t be said for both online and real life.
