You will not get banned in the process as long as you submit relevant articles, enough keywords/links and enough potential niche for your blog. Also, I would like to agree with Mark. You can find your keyword using Google insight plus create a blog on blogger.com with a Google account. Additionally, do not post too much words or those will initiate you to copy from some other's blogs.
Always remember to take notes, find ideas but you'll structure them yourself, making it all unique, and all from your mind. Also, add media to the content to let it describe more what you say.
