Why am I getting over 100 friend request a day all of a sudden?

This is really weird im getting about 70-80 friend request about every couple of hours. And what makes it even weirder is that most of them are real accounts. The people are where im from or we have a lot of mutual friends. Some are not real accounts which I point out and dont accept them but this is crazy. I went from 450 friends to over 600 now and they keep coming. Has this ever happened to anyone else? What should I do?
