How can I continue to contribute after 3 Minutes and it still do not allow to post

1. You posted the same, or similar, answer on multiple questions (5, I believe). Further, it wasn't an answer to the question, but rather appears to be a statement that you are having the same issue.

   If you find yourself wanting to post the same answer on multiple questions, STOP. They are probably duplicate questions and the others should be closed as such. When you gain more reputation, you can Flag or vote-to-close these questions. You should NOT, however, post duplicate answers.

   Regardless, these don't appear to be answers. You should read Are Stack Exchange sites forums? to get a better understanding of what is acceptable to post as an answer. Also see How do I write a good answer?.

   Your posts were deleted by a moderator both because they were duplicates and because they were not answers.

2. You also posted a "Test" answer on your own (same) question which was deleted by a moderator.

3. And you posted again, with something that wasn't an answer, on a question asking how to escalate a LaunchPad issue. You asked that someone respond to your bug report. This may mean that you misunderstand the site -- This is not a site that is managed by Canonical (the company behind Ubuntu). This is a Community site where both users and moderators are simply volunteers trying to help others out.

   This post was also deleted by a moderator, since it was posted as an answer, but was not.

4. Last year, you also had a post deleted by a moderator since it appeared to have nothing to do with the question that was asked.

At a certain point, a series of low-quality posts will trigger the system to block you from posting again in the future until you have demonstrated that you can contribute good content to the site. We as moderators and users do not know the details behind this algorithm.

The only way you can recover the ability to post is to improve your existing answers, then Flag them for review. As mentioned in the previous answer, please see What can I do when getting "We are no longer accepting questions/answers from this account"? for details.

As a side-note, I would encourage you to be extra careful about the quality of your questions as well. Keep in mind that questions about the site itself should be posted here on meta.askubuntu.com. You posted this originally on the main site, and it was migrated here for you. However, a series of low-quality questions that do not fit on Ask Ubuntu will also trigger a question ban.

You, as a new user, rapidly posted a large number of bad answers and you are now suffering the consequences.
