Been there experienced that. I realized that they are stupid, but after a while from their point of view, they don't want redundant questions. But still my questions were closed, but those were narrowly different from existing ones. I used this trick. create additional 3 accounts in SOF (have them in each browser like Firefox, Safari, IE) and you post your questions through your main account in CHrome. And then upvote from 2nd, 3rd and 4th account from all other browsers, to keep the question alive.
