Do not create a new account.
If caught, the new account will be deleted, and the old one will be suspended. We do not take it lightly when people try to circumvent the automatic limitations of the software by creating more accounts.
Moreover, one trend that you notice almost right away after becoming a moderator, is that the people who do create more accounts hardly ever improve the quality of their posts. So they just end up getting more rate limits, they create more accounts, and the cycle continues. Some people are okay with that. But this shows that they have the utmost disregard to the community and ecosystem of this website.
Do not delete questions.
While we do not know the exact algorithm that puts users in a post ban, we know that deleted posts count massively towards that. What's worse is that you cannot improve deleted posts, so their weight just stays there forever.
Waiting is an option, but not a great one.
There are "short bans" which can be for a day or three or a week, and there are "permanent bans" which tend to go for six months or longer. If you simply wait, you might have to wait a long time.
What's worse is that the more bans you've had before, the quicker it will be for you to get more bans. That means that if you waited out the ban, and finally posted a new question, then the slightest hint that the question is not perfect will throw you back into the ban, possibly for an even longer period. And again, we don't quite know what these things are, but even a single downvote might do the deed.
Improve your posts. Yes.
The goal of a post ban is to give you time to reflect on what you have done wrong, and to look at posts that are well-received. On this site, that means learning to use MathJax properly, and writing a clear question with all the necessary information.
Eventually, this will improve your asking abilities, which is a great skill for life in general.
While I don't know off-hand if that can get you immediately out of a post-ban, it will certainly help to keep you out of there once you get yourself back on track.
So what can you do?
Your account shows four downvoted questions, and four deleted questions (one question is both).
You should improve your downvoted questions, and you should undelete your deleted questions. Improve them. And if you have found answers to them, post answers to your questions.
While this site is not meant as a personal blog, or a place for people to write out their questions only to answer them soon thereafter, it is better to have good questions with good answers, even if you posted both.
In the future, try to write down the question properly, then leave it for a day or so, clear your head, work on something else, do the dishes and clean the house. Come back the next day, re-read you question. If it's really something trivial that you've missed, you're likely to find it yourself.
