How does the "censorship" on this website work?

I have attempted to post a question twice, and it doesn't appear on the immigration link, but it does appear in my questions asked. I have asked for and received responses from a few people regarding this and they also don't know what's going on. If the moderator is going to delete question(s) for whatever reason, shouldn't the poster at least be given the courtesy of telling him and explaining why?? Has anybody else had this problem, and what did they do about it?
