How do u ban a person that users my-lite accounts & that was previous ban by xbox

To be clear the console was not previously banned. Worked on xbox live for 3 months before it got banned. How does this work? Does any console that a banned user has had as a 'home xbox' get banned or whats the deal? So essentially is every used xbox in
jeopardy of getting banned based on the actions of the previous owner that are still some how associated to the console?

Can I still be banned if I purchased an Xbox console second-hand?

Yes. The warranty on a second-hand Xbox console is void, and the purchaser assumes the risk for any previous modifications or unauthorized activity. Even if the console’s ownership has changed, the console may still be subject to
a ban. If you purchase a console that has been previously banned you will not be able to connect to Xbox Live, and the ban will not be lifted
as a result of the change in ownership. We recommend customers who believe they have not committed actions on the service to warrant a ban to contact previous owners or users of the console.

You got banned for chatting and sending bad message and that is really done without mic.

There is no such thing as to speak with a person inside Xbox to sort out a ban, most ban's dont happen quick it can be from a previous action.
