Looking for potential future account advice

Someone in my household set up an Amazon seller account but then a competitor complained that they were selling their product and it got suspended they then (for some reason) decided to open another account and sell the same stuff at the same address and Amazon saw that and suspended that one too. They asked and were told by lawyers their account would be toast. I didn’t know they had one for this address till a little bit ago. I was wondering since I’ve been thinking about opening one for a while selling something completely different if it would be possible under the same address or if I’d need to wait some amount of time or if that’s a terrible idea and I should wait till I move elsewhere
