6 months or more to asks another question is extreme just for asking bad questions which I thought were good. Once the asker is up to a point of bad questions regardless the length of time that passes the next poorly received question equals another 6 month ban??? I am sure I am not the only user who feels this way and I ask for not just me but for every future novice engineer enthusiast who may get stuck in this rut.
Question bans are controlled by the SE systems / algorithms. Moderators do not have the ability to override the length of those bans.
SE typically follows a progressively increasing length of bans or suspensions. You may find the following Meta StackExchange post of relevance as it goes into a bit more detail about question bans.
When you get banned due to excessive low quality posts, you get a explanation of what to do about it. Follow it.
Note that pleading for the system to make a exception is NOT one of the recommended actions.
Remember that you were banned for substantive reasons. You have done nothing to show us those reasons no longer apply. In fact, this question re-enforces that they probably continue to apply.
