By uploading your key with your real name and email address in it, you are telling everyone in the world that you exist and what your email address is. You are also inviting unwanted email when you do this. I have received such email. I also don’t believe in signing keys on keyservers. This simply creates a ready-made list, that anyone in the world can read, of people who know you.
