Question: what happens if you block someone you're in a snapchat group with?
Answer: From Google search: 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. ... Yes, because the Group is public and all members in a group chat don't necessarily need to be friends actually. New friends can be made in groups.
