Because everyone posts their beautiful images on Instagram but no one shows their bad hustle behind it.
On Instagram if you want to spend some time there it not so easy, because the algorithm of Instagram shows you the better results to stick to that, so that you spend more and more time there and becomes habit of it.
Obviously I don't want it but I use it because the instagram has the large userbase and for digital creators and marketers it gives the opportunity to showcase their talent.
There is worse reality that so many younger are get addicted to it. That's why every parent want not to use more time with smartphone.
Some of the accounts on Instagram are continuously spreading fake news there, many more pages are only for like for like, forwarded posts from other pages are get shared, no one creates real posts, the reality far away from the digital activities on social media.
