Has anyone worked out the percentage ?

I'm sorry Rose, but there's is such a huge amount of questions, ever changing, ever updating or dropping off. It's impossible to determine percentages....I myself just simply look for legit questions, and I for one try to give legit answers. It's just like dealing with society for real...there's good people, stupid people, and jerks. You just need to sort out the ones you are willing to interact with. Take heart, there are SOME real people out here.
