my friends FOR SURE blocked me but i wanna know for sure for sure. is there a way to tell? like 100% confirmed they blocked me vs just deactivated or something. asking before i do something embarrassing 
If you want to be 100% sure try clicking on an old DM or a comment where they were tagged. If their profile pulls up but it says “account not found” or looks totally empty and you know for a fact they post videos you’ve definitely been blocked.
