Your reputation does not translate between sites. It is up to you to show that you can ask high-quality on-topic questions on each site.
You have asked a total of 17 questions on this site

As such have received an automated ban. This is entirely enforced by the system and when you attempted to post a question you should have received a link to the page regarding question bans. If not then go to this page and carefully read everything there. Specifically
At Stack Exchange, asking questions is a privilege, not a right. If a user cannot demonstrate, after asking a reasonable number of questions, that their contributions are making the site better (or at very least, not making it worse) then they will be blocked from asking further questions until they have demonstrated their ability to contribute positively.
If you're unable to improve your existing questions, you'll get the chance to ask a new one 6 months after your last question. If that question is positively received, you may be able to continue asking questions; if not, then the ban will be reinstated.
