In this case, the forum acts as a fraud, as well as the previous owner of the account. If trade in accounts is allowed, then there must be order. Rules create for their execution, for all right? As I understand it.
If you buy a car from a stranger, and you are shot for it on the street, taking for the previous owner. It is right?
No, that analogy is not right. A better analogy is if the previous owner threw sand in the crankcase causing the engine to blow up some time later after you bought it, then blaming the car's manufacturer for allowing used car sales. The moral of the story is, when buying a used car from a stranger, check the oil first, if only to make sure it is in fact oil and not sand.
