It's a no no for me. Bcoz before I had a relationship thru txt only. Obviously I dont know much information about my txtmate I though it was a girl but it's actually a freaking gay. I wouldn't know that until my classmate told me that a gay friend of someone in my school gave my number. So I was like.... YUCK! I also suggest not to make contact to someone you actually dont know or never met before, coz it might held to a bad situation.
