I don't understand your first question. From the message alone (which at the time seemed to be 'official') it seemed there was nothing of interest, so was quickly dismissed. And nothing has changed that AFAIK.
The point which I think you've missed is that this was represented as a communication from the company itself, not a non-employee.
If it's more likely in your mind that it's a company of sixth-graders, go for it, believe that.
