StackOverflow is no longer accepting questions from my account. It happened after I posted a question asking for comparison between PHP and C#. The question was deleted and my account banned. OK, I get it. Maybe, that makes me a help vampire. I got downvoted like anything. It should have deleted it before SO did that.
Now this Meta SO page says the ban might be uplifted by writing a few quality answers that get upvoted. Since then, I have posted many answer some of them were also accepted and my reputation has increased by 200 or so. But still it won't accept my questions.
Does anyone have any idea how far I need to work up so that I can get this ban uplifted. They say a few answers... But that doesn't seem to work.
