Myself and most people I know don't really like people they don't know adding them and trying to talk to them. There's so many spammers and account hijackers out there why not protect yourself and your account from adding literally anyone. If people I have never met before cold request me they usually get blocked. Why? They are not friends and they are not family. They are unknown parties with unknown intentions and I honestly have no time for people who send requests without ever talking to me. Want to be my friend? Talk to me first, you know, like I'm a person. If someone doesn't they either rot in the place between accept and reject or are blocked.
