I succesfully re opened a closed account, what are the risks?

Hi, I don’t know what to expect. I sold FBA like 6 years ago for a few months. Never got paid (Small amounts) good health account. I asked to pls close the account, even though they asked me time to resolve, they confirmed to closing it vía mail. Now I want to sell again, so in my understanding to reopen is not possible, the thing is that my loggin for seller was semi-functional, means I loggin with same mail and phone pswd from 6 years ago, (maybe because same as personal account to buy?) well it let me in. Then I was asked to fill all the info (like new seller) id verification, etc. The true I was expecting in all this process to be Able to appeal to reopen, but just got the message that my account is active to sell. I already filled the tax info, the deposit info, and it was accepted. Alll the info from the past is errased except the name I used internally within the platform (I already change it)

Should I contact them? I know they can suspend if it was a new account and some how linked to the old one, but this is not the case… but still I am afraid of future suspension. I was planning to do a new account for an LLC, but it was too risky for any linked information. Sorry for my English not native speaker.
