Hello @Lily,
thank you for joining the forum and welcome!
Unfortunately, what you described sounds like a very bad idea. Many sellers make this same mistake and rather than maintaining one strong and established account, while fixing any issues, they keep creating or adding many more accounts to their portfolio. These accounts are not established and are easy to get suspended. This then creates a rabbit hole of eternal and continued suspensions which are at that point impossible to solve.
If I were you, I would focus on fixing the first account that got suspended. Otherwise, you will be on a road of losing lots of money and progress, every time one of the newer accounts gets suspended and you will also lose your FBA inventory and withheld funds.
