How can I ask the right question so that I don't get banned?

Recently, I have been asking several questions about SML/NJ. For some reason that I do not understand, I got banned (reached my question limit).

My Trials:

1. I read the entire forums and advice that was given, tried to apply some of them, but to no avail.
2. I asked some friends for a tailored advice by giving them my question and how should I enhance them and they gave some advice that I applied, but still to no avail.

I do respect the community and totally understand that asking a question is a privilege not a right and I will never try to bypass such limit because it was set for a reason. I am just trying to understand the reason so that I do not repeat the same mistake over and over.

These are my questions:

1. Why is foldl signature is a pipeline instead of a tuple like type in SML?
2. What is the effect of adding a variable type binding in signature in SML on the Module?
3. Why does "not" care about "List.exists" input in SML?
4. Forward Display from docker to host
5. the read function in my socket API does not work and lags

I have discovered that there is a bot that deletes questions automatically and some contributors linked them in comments.

1. When to use circular recursion and when not to use it?
2. Failed to use SFTP over different ISP
3. laptop screen not detected on Kubuntu
4. is there a solution for using more than 3 keys for shortcuts on Ubuntu with KDE installed?
5. why doesn't the thread start?
