The problem is that you can&#x27;t prevent a stranger from sending you something you don&#x27;t like, unless you block all strangers from sending you messages or block the stranger after they&#x27;ve already sent it.  You reported the person to Instagram.  In my experience, this works pretty well and the user account will most likely get banned.<p>I feel like you want a digital &#x27;safe space&#x27; like on many college campuses.  The real world is much darker than this.  There are no safe spaces.<p>The &#x27;edge case&#x27; that you discuss is just reality.  The only way around it is to only communicate with a circle of people that you completely trust.
