To give somebody your bank account details to pay you by bank transfer? To somebody random who's bought something from you on ebay?
I say not, as it's only the same amount of info as you give somebody if you pay them by cheque. Mrs aracer points out that you don't give somebody random on the internet a cheque (a point I'm struggling to refute), and isn't happy.
Is it realistically possible for somebody to do something with the details you give them to make a bank transfer?
