Question: if you block someone on snapchat do they still have you as a friend?
Answer: When you block a person on Snapchat, they won't be able to look at your Story or Group Charms. They also won't be able to send you Snaps or chats. So, assuming they don't have another way to contact you, and they aren't friends with you on another social media site, blocking will cut them off from you.
