When someone adds you to their Contact list, that person is your Fan. The best way to grow your fan base is to ask, answer, and star really interesting questions.
If you’d prefer not to have fans, you can opt out of this feature. To restrict people from adding you as a contact and becoming your fan:
Please note that if you opt out of this feature, all your existing fans will be removed at once and will not be accessible again.
You will continue to be able to add other people as contacts and become their fan even if you restrict others from adding you as a contact and becoming your fan.
