Deleted my Life Invader Account 6 yrs ago and don't regret it. I know many others that have done the same thing the past few years.
Main reasons I did, got tired of seeing peoples kids pics everyday multiple times a day, we didn't forget what your kid looked like yesterday or the day before or the day before that. Seeing people post pics of their nasty feet at the beach propped up on a chair. Seeing pics of what everyone had for breakfast, lunch and dinner. SELFIES, I don't want to see your face everyday in my newsfeed.
Just to name a few.
