How do I stop someone from following me on twitter?

You can block people from following you quite easily. Simply go onto their profile, and next to the 'Follow' button will be another button with a mans silhouette on. Click that and a drop down list will appear. Simply choose 'Block' from that list. Of course there is nothing stopping them from creating another account to follow you with, but this is the best way to do it if you do not wish to add settings which affect other followers.
