I've spotted an unusual user. Long story short they ask tons of questions (normal) but almost exclusively answers questions they asked themselves - is this behavior normal/acceptable?
The user I have in mind (I don't want to finger-point so I won't link to them) has asked 10 times as many questions as answers - normal; it's their right to ask a lot of questions - but of their answers, less than 20% of them are in response to someone else's question - the other 80% are answers to their own questions.
So less than 2% of this user's total activity (only about 10 answers) actually involves other users in the community! I hate to be one of those people, but I gotta admit I'm a little impressed by how much rep they've pulled in with this very introverted behavior!
Is this normal/acceptable user behavior for a StackExchange site? Are there any guards requiring a certain level of "participation" with the rest of the community? Should there be?
