I take extra care with all transactions now as I had my identity stolen at one point. Someone had hacked into my computer, despite the Firewall and managed to watch my transactions on line...they then took over my E-mail, my Ebay account, rifled my bank account, used my credit card to buy items on the internet, etc............I felt so abused!
There will always be a chancer who will take advantage of an opportunity...all we can do is try to minimise the opportunity I suppose.
Best wishes, Mike.
