Facebook

I've only just joined and only have a couple of contacts so still getting used to it.
But I am spooked by a long list of dozens and dozens of "people you may know". I don't like it. I've never heard of any of them. Most of them have 'middle eastern' names (sorry) and I don't know how to stop them. If I delete them all I'm inundated with loads more within seconds. I feel like closing FB down because of it.
