Asking for a relative.
She has over 500 followers. For a while now she gets a follower with no profile picture, no followers. not following anyone and no posts. Is this something that happens on Instagram? She blocks these people for a personal reason. There is only ever one of these at a time. A few hours after she blocks them, another one pops up.
Trying to work out if this is normal social media rubbish with an explanation or something else.
Thanks.
