There should be allowance for users who have been blocked by someone the same privilege to block them back. As it is if someone blocks you they completely dissapear. It happens occasionally that I tee up a meeting, After agreeing on a time and place I then take about 1.5 hours getting dressed up and ready, the meeting time has come and gone, I log back in to find the user has blocked me, and I'm unable to block him back, which leaves the person who got blocked vunerable to this kind of behaviour from the same person again and again. Which may be what has happened a few times. Can we fix this, so we have a way of stopping this bad behaviour.
