Question: can you block someone on snapchat if they are not your friend?
Answer: Unlike with Facebook, blocking someone on Snapchat who isn't already a friend is a little tricky. ... Set the privacy settings on who can send you snaps, to do this, tap the ghost icon when you run snapchat, and then tap on the settings or gear icon. Scroll down until you saw “Who Can” section, and tap “Send Me Snaps”.
