@blue-magoo I'm not intending to create anxiety. But everybody needs to know the internet and the web are dangerous places. At time progresses more and more care needs to be taken. The scammers are far cleverer and more committed than those few trying to clean the place up. There is nothing that can be done and the experience will get worse and worse. They sure opened a Pandora's box when they started the internet.
People here rightly say you should always get in contact and talk with people you deal with. But over her in Blighty the largest and most widespread scams are financial frauds where very plausible criminals do just that and convince you they are genuine. Billions are lost every year.
The rule has to be: if you are in the SLIGHTEST DOUBT WHATSOEVER immediately walk away.
