The question should have been, What kind of stalker is stalking you

there are two kinds:
A- One who gets to know you, a normal kinda guy at first, he develops a love for you but you reject him. It is not easy for him to accept that, so he hangs on to hopes that may be one day you are going to change your mind about him. He convinces himself that you love him really or loved him, he is confused

progressively, his obsession and stalking is on and off depending on how friendly you are towards him. With his kind of STALKER, you can get rid of him by not being nice to him at all. No matter how difficult it is for him to leave you alone, it will dawn on him that the well has already dried and he is gonna die of thirst if he doesn't move along in search of water to survive
B- The second kind is sick, you don't KNOW him or barely know him, nonetheless, he makes your life miserable enough for you to seek the help of others to stop him.
Hope that helped.
PS: For the first one, if he is gentle and nice, you will be able to handle him, the second is dangerous and you should confront him by accusing him to anyone you think will stop him from contacting you. If he is Somali, and you know his family or other relatives whom he respects, may be they can talk some sense into him, Or his friends. Good LUCK.
Bye Now.
