You can always just block that person, then whenever they try and search for your name on Facebook, your name won't appear at all. Safer that way.
You can also in the account settings section, tick the box where it says, do not create a public listing for my account. But the problem with this one is, some of your real friends might not be able to find you as well.
In the end, just ignore any messages or friend requests that you don't know, as with any other internet websites etc.
