Don’t want to hear from someone, but you’d rather not block them? Try out Instagram’s Restrict feature. When someone is restricted, they can continue to be your follower, but you essentially won’t see them, or hear from them.
They will be able to message you, but you won’t see the messages. Their comments will only be visible to them, and not the public. You’ll have a choice to view a restricted comment, if you like.
To restrict someone, open their profile, tap the Menu button, and choose the “Restrict” option to get started. You can “Unrestrict” someone from the same menu later on.
