Their online status and activity status may no longer be visible to you
Your comments on their posts may only be visible to you and not to others
They may not appear to be responding to your messages
Messages you send may show as delivered but not read
Their posts, stories, or profile may still be visible, but interactions may feel limited
You may notice fewer signs of engagement from them compared with before
You may be unable to tell whether they have seen your story if they have restricted you from viewing it
Their likes or comments on your content may stop appearing as expected
You may still be able to follow them and view their profile, but with reduced interaction
The clearest sign is a consistent change in how your comments, messages, and interactions appear to you
