I don't think anyone is being "bashed", simply told not to be an alarmist.
Stuff happens that the suppliers can't control - watches get damaged in shipping, customs hold-ups, unseen damage etc.
Not giving suppliers a chance to respond paints an unfair picture, the problem may well be something they have no control over. There will be plenty of time later to report "I had a problem and X resolved it quickly" or "I had a problem and X did nothing" But by jumping the gun and reporting too early you can make a good, responsible supplier look like they are unresponsive when they in fact are doing their best to keep their customers happy.
By all means, report on your transactions, and don't forget to report when you have a good experience as well.
But you can't do a movie review if you've only seen the first five minutes of the film.
