What Happens When You Delete Your Instagram Account?

Image
  As Social Media platforms like Instagram gained tremendous precedence over the last decade, our lives also began to get tangled deeper with the virtual. While many GenXers and older GenYers began focusing on creating and maintaining an online presence, seeing both professional and personal value in this activity, our children and young Gen Xers don’t even require any kind of intent. This is the norm for them now. The point is that the line between real and virtual has been steadily disappearing over the past decade. While there are those who have not just accepted but are also thriving in this new world, there are those of us who are simply not cut out for this. Because for all the good that it’s doing, Social Media is also extremely addictive and not everyone is cut out for it. With users looking for an out by deleting their accounts and thus living an Instagram free life, we would like to make this transition to a social media-free life easier. So now that you’ve left Instagram...
