As a friend: Sure, you don’t always have to see them in person, but if they ask you about personal things like your age and stuff, I wouldn’t risk it. Being in Love: NO WAY!!!!! If you haven’t met this person in real life, there is no chance. This person on the other side of the screen could be a child abuser or murderer (I dunno) and ask you about personal stuff (like take photos of yourself) block him straight away!
