How do people find you on kik?

Okay so I wanna make a kik on my iphone cause a lot my friends tell me too, but there's like a couple of guys I don't want to have it cause they have a crush on me and they text me all day so I don't want them kiking me too. So how can I disconnect it from my contact list, I'm not gonna add my Facebook friends or anything. I only want my close friends and whoever I give it too, so will they find me through my contacts and how can I disconnect my contact list from kik?

They find you because you/somebody have given/shared your kik messenger ID publicly, i mean the ID what you signed up for kik messenger. Thats it, tap on them for some time and remove/block them.easy.btw don't share your ID with strangers.
