Whenever I post a question (usually on Stack Overflow), I almost always get a downvote within the first few minutes of it being posted. I try my best to follow all the rules, search before posting, and correct formatting of the post, but when I ask for help, now I am greeted with the "Careful what you post, you might be banned" message because 2 or 3 of my questions have 1 downvote on them.
I think users should be required to provide a reason, or at the very least a comment describing why that they think the content shouldn't be on Stack Overflow and/or isn't useful. This would help encourage new users like me to contribute content that could help, rather than hold back in fear of getting post banned.
