Irresponsible posting is the problem. By naming a specific forum it allows people to change chat apps and feel guilt free.
And one of the names initially mentioned as killed B”H survived (and even those that didn’t weren’t yet declared dead when the messages started flying.) So the lesson here is: in times of tragedy never try to be first to report about it, all the more so if you have no real clue what’s going on and are just parroting information.
Some people call the fact that the child wasn’t notified sooner lack of communication, without realizing that someone must find the right person in close proximity to break the news gently to each family member, and IN PERSON. Very often next of kin is first told that their family member was hospitalized without mentioning that he/she has unfortunately already passed away — to not shock them. And if the person has health issues there may need to be a Paramedic nearby to administer medication if warranted.
May we only hear besuras tovas and happily broadcast the news!
