Blocking a user on Instagram has specific consequences regarding message visibility. When an account is blocked, the message history between the blocker and the blocked individual remains accessible in both users’ inboxes. The messages do not disappear retroactively from either account as a direct result of the block.
This behavior is important for maintaining a record of past interactions. The existence of the message history can be relevant for personal reference or potential evidence if needed. Furthermore, the retention of these messages reflects Instagram’s design choice to not alter past data merely based on a user’s current blocking status.
