I just joined Twitter last night and immediately there were several, I assumed, "suggestions" for who I should follow. I rejected all of them. Well, this morning I find stuff from them on my page as if I'm following them (I'm still figuring out the terminology). For example, I rejected The Onion, but I have stuff from the Onion this morning. Also, some people are able to connect themselves to me without my permission. I went in and blocked some of them, but there's one person that no matter how many times I click "block" I can't get rid of them. How do I solve these problems?
