When I am posting my question I am getting the following error:
Sorry, we are no longer accepting questions from this account.
What can I do?
I think the problem is not simply related to your poor English, which can still be excused.
However, you have put no effort into asking your questions. I have read the first 3 and all of them are vague, and I am truly surprised they haven't been closed. I would suggest you take some time to read Jon Skeet's guide to writing a perfect question.
Here's what you need to do, take a few days and read other's questions, watch how the community responds to those questions, and what they respond to negatively. Write your question in notepad first and rewrite until you feel that it meets the site criteria, and then post your question.
Also once ready, email [email protected] to have you IP unbanned and allowed to post again. They could potentially ask you for a sample question to determine if it is truly valuable to unblock the IP. However, emailing them right now won't help, since your questions still meet the criteria for throttling.
This happens when an IP has a history of asking very poorly-rated questions, which yields a permanent ban of that IP address.
This is a permanent ban. It not only blocks your account, but also the IP address you were using. To prevent bypassing the filter, its exact details are not public. It is partly based on downvotes, and downvotes on deleted questions are also taken into account. (An account with a high public reputation might very well have many deleted questions, including auto-deleted old low-score questions, all of which are only visible to moderators.)
I got mine blocked from asking new questions on meta. I have asked 3, one of them got -15, one a small minus and the other a small plus.
Hardly a history of asking poorly-rated questions, plus on meta a negative rating does not necessarily indicate a poor question so perhaps that rule should not apply here? Especially on such few questions.
No chance of asking good questions now.
And no point in e-mailing as nobody replies.
