You have two deleted questions, one heavily downvoted. From looking over your profile, this does seem like a borderline case. Meaning, you're not in too deep.
If you read through What can I do when getting “We are no longer accepting questions/answers from this account”? carefully, you will find a couple of tips for getting unbanned, including:
The only ...
I'm a moderator at superuser, and I'd second that this happened due to the cold hard logic of an automated system, and the moderators didn't really have anything to do with this. MSU would have been the right place to ask this since I found this by accident (Question has since been moved to SU) and you wouldn't have gotten a response from the folks who'd be ...
Its not one question - you have about 4 deleted questions as well, automatically deleted because they are zero or negative scored and have no answer.
Question bans are automatic. Mods can't question ban you or lift it, though you get a chance after 6 months to post a question.
While there are ways to appeal a moderator decision, literally zero moderators ...
You have three deleted, negatively scored questions:
Desktop PC with no moving parts, -3, from February 2015
What is in C:\ccmcache, -1, from July 2014
Accidental deleting my mailbox, NSA help needed, -2, from December 2013
The 2nd question could have been answered; it seems you self-deleted it after only 5 minutes when it got negative votes. You could ...

Of the 10 questions you've asked:
2 were deleted (both were downvoted)
3 (different ones) were closed
Only 2 have more than a single upvote, and one of those is closed
Moderators are not privy to the exact algorithm behind the question ban, so I don't know for sure, but you're probably right on the edge. In case you weren't aware, deleted questions still ...
You have three deleted answers. All your answers posted promote one product without disclosure. This is considered as spam and abusive – under normal circumstances your account would have been placed in a timed suspension or deleted altogether.
See our help page:
Avoid overt self-promotion.
The community tends to vote down overt self-promotion and flag it ...
It's not 'the last question' – 6 of 10 of your questions were deleted. Sometimes we notice and manually send a message, there are question ban warnings, and one rarely gets suddenly banned from asking questions.
If we must, let's look at why you got question banned – not only are 6 questions deleted, some are self deleted, and this sort of thing is what ...
I have only asked 2 or 3 questions
You have asked 10 questions.
Is my status on other SE sites causing me to have a premature question ban here?
No. Your status on other SE sites makes no difference to your status on SuperUser.
On SuperUser you have asked 10 questions.
Those 10 questions have a total of 18 downvotes. Only 1 question has an upvote.
8 of ...
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
9 of them have been deleted
5 were closed or migrated
only 2 questions have positive votes
4 questions have a score of -1 or less
As such have received an automated ...
Your questions on Super User currently are a net zero in votes with a wild variety in quality and formatting issues. This leans toward your account being blocked from asking new questions for now.
Compare that against your Stack Overflow profile where you have a lot of old questions that are also in poor quality, but because they are old now have a lot of ...
The warning fires even if you're not close to being blocked, and you're definitely not anywhere near that edge. The reason we do this is we want to encourage people to edit wherever possible, instead of delete.
Your questions are generally well-received, which means the automated block is something you're extremely unlikely to ever encounter. But, folks ...
Could some one list the business rules clearly?
Bans (question or answer) are automated and nobody knows the exact rules (which are kept secret to prevent users from playing the system).
I can see that someone down-voted one of my questions. Is this so bad?
By itself, no, that is not so bad. However, you have asked 17 questions (of which 9 have been ...
You've asked two questions:
One that was migrated to Unix.SE on your own request where you then deleted it (so this counts as a rejected migration on our site)
Another one that was closed as primarily opinion-based and auto-deleted later
Basically, two closed and deleted questions, which negatively impact your account's standing.
Deleting questions voluntarily never helps you, it can only hurt you. If a question is really bad, a moderator or a bunch of high-rep users with the "Vote to delete" permission will get it deleted.
Basically, your question remaining on the site is an indicator that it has some value, even if that value is only to tell people what isn't on topic. And as far ...
You have asked a total of 14 questions on this site, two of which were last august and were migrated to GIS (1)(2) and another in march that went to Android. Prior to that you have a deleted question and a two closed duplicates.
It is possible that you are on the edge of hitting the automatic ban (which we have no control of) and the detection system is ...
You have asked a total of 14 questions on this site, of which only 6 have remained open or not been deleted. Many of your deleted questions were downvoted, ignored or otherwise off-topic
Your current question is of good quality, so may be helping you, but it is entirely possible that you have been rate limited by the automated quality ban system. We have no ...
None of my questions have a score below zero. And I can't see my old deleted questions.
You have asked 30 questions (15 are deleted).
Of those 15, 5 have a -ve score and count towards your question ban:
Reading your deleted questions you have the creativity of Wile E Coyote, but you don't appear to have done ANY of the homework necessary to begin to turn those crazy and creative ideas into good questions.
First, I suggest you read the Help section to learn the few rules that govern this place and the many suggestions for how to write good questions that ...
