This question already has an answer here:
Questions like this are fairly common. New users sign up, treat Stack Overflow like a forum, and wind up with a suspended account. They then post here for help, and a moderator ends up writing the same explanation that was written the last time this came up.
Can we do a better job about warning users that their behavior is starting them on the path toward Trogdor? After, say, their first two posts are flagged and deleted can we throw up a red warning banner at the top, linking to a page describing what kinds of posts are acceptable (and unacceptable) here, and warning that they're on the verge of being suspended?
and probably a duplicate of Give better explanations when accounts are blocked
