Anyone ever been banned from trade from spoofed account?

Let’s say for example you have your main acc, you don’t spoof on that and it’s always been legit.

Then you go and make an alt account to spoof fly and collect mons that you want and trade to your main.

My assumption is that’s completely safe as let say you did a trade in real life with another stranger at a physical event, and you didn’t know they were giving you a Mon they spoofed, it would be totally unfair to the unknowing player correct?
