Well, you were suspended last time around for posting low-quality questions (which are a problem because they create work and annoyance for other members of the site) and making scores of edits that didn't substantially improve the posts being edited but did clog the active lists with questions that folks had already seen (which also creates work and annoyance for others).
So... If you want to avoid being suspended again, don't do anything that creates work and annoyance for other users:
- Put more thought and research into your questions before posting them - if you can't formulate a clear, well-researched question, sit on it for a bit until you have the time to flesh it out.
- Put more thought into your edits before submitting them - if you're not sure the edit you're about to submit makes a significant difference in the quality or content of the post you're editing, don't submit it until you have an edit that does.
