This is odd, but whenever I try to follow people, my list then says that I'm not following anyone. Is this a bug? Did I forget to configure something? I followed quite a few people, but then the list says zero. My account is not suspended either. What can I do to fix the follow friends problem? Any help would be appreciated. Thanks.
Not sure how many people were you trying to add at once or if any of those had filters where they have to approve you first but here is a list of the common issues regarding Following from the official Twitter site: https://support.twitter.com/articles/20169379-common-following-issues Hope that helps!
I will recommend you to follow them one by one. Never notice such issue before. So please give another try
