ThomasOwens addressed the reason for the temporary question ban. I would like to address the reason for the reason, that is, why your previous questions led to the current situation.
Note that deleted questions are only visible to moderators, 10k users, or the user who asked them.
Rightly closed as primarily opinion-based and deleted. This is speculation that cannot be answered objectively.
Invites discussion (not answers), essentially asks for career advice which is off-topic.
Asks for advice on how to deal with coworker situations. Off-topic and subjective.
Asked on the wrong site, self-deleted.
Asks for a software tool which is explicitly off-topic per our help center.
Okay question about source control. Probably better-suited for Stack Overflow because it is asking about source control software, not strategy, but I wouldn't close it.
On-topic, but probably a duplicate. It is also a bit verbose.
On-topic question about software process.
On-topic, but on the verge of being too broad. Still, it is about software organization and development processes so definitely on-topic and rightly does not have any downvotes.
Asks for help configuring a software tool. With more details it might be acceptable at Stack Overflow.
Now for the important part: constructive feedback. Once you are able to ask questions again, I would focus on these items:
I see a few "soft" questions asking about opinion or how to convince a teammate about something. These questions are off-topic, unsalvageable, and unfortunately for you are simply not a good fit here.
Questions that belong at Stack Overflow. Some people have a difficult time understanding just where the line is between the two sites. I agree it can be a bit blurry at times, and it is fine if you post incorrectly but in the gray area. We can fix that.
Which computer science / programming Stack Exchange do I post in?
What are the differences between Stack Overflow, Programmers, and Code Review?
A small number of off-topic questions that simply fall into one of the off-topic categories in the help center.
Why was my question closed or down voted?
Several of your questions are very verbose. Try to focus on one thing, choose your words carefully, and describe the problem fully but in less space. This will help encourage us to read the question more fully, understand what it is asking, and hopefully upvote it. If the question needs improvement, it makes it easier for us to edit it.
