I have read What can I do when getting "We are no longer accepting questions/answers from this account"? but I need to clarify something:
I was banned from Stack Overflow when I was a new user. Since then, I have been quite active on several other SE sites, and have received quite positive, useful and green reviews.
Do I have to get more reputation and points on Stack Overflow specifically to get out of my ban, or does giving positive feedback and earning reputation on other SE sites help with this?
