One of the first things one learns when running a social network, usually the hard way, is that there are actual people that thrive on upsetting as many people as possible, and on trying to destroy the good things others have spent time building.
But that's not a surprise.
What IS surprising to me however is that so many people in our circles are vulnerable to this type of exploit. I even see some querulants trying to convince others that "ZeroNode will fall."
Don't get fooled. Choose love.
