How do I erase all the questions in the "My Questions" page?

Why arent my questions showing up on the main category page?

• I have posted this question under polls and surveys and it got deleted. i dont know why. it wasnt chatting or anything. i WAS seeing knowledge, maybe someone knew from personal experience. who knows? i never got to read any of them. anyways, i'm still trying to post up questions and i keep refreshing and other questions are going and mine arent. they are still open, have not been reported/deleted but why doesnt it show up on the front page?? i really dont understand how when i ask a question, it wont go through, yet i see SILLY questions going through perfectly fine. Can someone please shed some light as to why its not working? I read one answer from someone saying that its because yahoo prescreens questions to see if i'm trolling or chatting, which i was neither doing. and i seriously doubt because i've seen HUNDREDS of trolling questions and have never been removed.

• Answer:

  Yes, there IS a prefilter that might have delayed it. It is NOT perfect, so many things still go through, but it does catch LOTS of questions. The prefilter checks for things like: > links, especially multiple ones > language (specific trigger words / phrases) > over-use of punctuation or CAPS (which might indicate swearing or ranting) > prior violations in the category > multiple postings of the SAME question > random other things nobody except the programmers know about If any of the above trigger the program, the question is supposedly held for staff review - or just not posted. You can try adding additional details of a number of periods (........) and see if that pops it into the list. You can wait patiently. Or, you can delete it, figure out what the problem might have been and repost it with improved wording and see if that helps.
