We are no longer accepting questions from this account
I got this notification a month ago when I tried to ask a new question. I read the FAQ and understood why I got this ban and how to get rid of it. I started contributing positively to the site after that. I fixed the posts that I think caused the ban (some were edited, some were deleted). Some of the edited posts got positive votes. Also, I answered some questions, and one got accepted, one got up-voted and no answers were downvoted.
So, what can be done to get rid of this ban?
P.S. There are two questions -- one on-hold and other closed. I've just edited them but I can't delete them as they're having answers.
