The message you're seeing comes from a recently implemented question rate limiting system, which you can read more about in the Help Center. In particular, please note:
If you haven't yet done so, please read our advice on how to ask good questions, and the types of questions one should avoid asking.
This block is only temporary, but much longer blocks exist in the system. We're trying to slow you down and provide you with more guidance now, in hopes that you avoid a much longer period where the system won't accept questions from your account. Please take some time to revisit and improve your previous questions wherever possible.
You'll be welcome to ask questions again soon, but please make sure you research your problems prior to asking, and ask only when you're really stuck. When you do need to ask, be sure to follow the guidance we've provided and everyone will have a much better experience.
Why you are seeing this message? You actually have asked two questions on Server Fault.
The first question you asked was wordpress multisite failed to import media and users. This question was downvoted to -2 and automatically deleted by the system after 30 days with no answers. (I think this question would be better suited for our sister site, WordPress Development, but I never saw it originally and it's too late to migrate it.)
The most recent one was Update ubuntu automatically. This question received both an upvote and a downvote, making it eligible for question rate limiting.
