Well 2 problems surface here ...
..the fraud-
- is bad enough . Somebody breaks the Law and can be identified then although nothing is 'clearly cut and dried ' , you are okay to persue them legally - the Police and the Courts . Real fraud - this happens very rarely .
- Making payments easily and cheaply is the most important and when I see people demanding Bank Transfer only I walk away - I have no idea where they bank , but when I inquired at mine , was left with the strong impression that it was unsafe by the staff , and also very costly . There is also the issue of my details being accessed by a third party ...fraud .

So nobody gets my Bank details - I use Cash or Paypal .
If an accident occurs and payments go ascue then yes its frustrating and a problem .
If fraud occurs then see note above and I stop worrying .

How this really REALLY affects us all , is when on national / international forums , people refuse now to post - face to face only .
Defeats the purpose of the Internet . I can afford to lose a little money . I cannot afford to lose out on a needed item for my collection - because somebody refuses a sale .
