You know why people dont like facebook ? Because they fucking manipulate people.
Large social experiments are conducted to manipulate opinion of people.
How ethical is that ? You must be some shill for facebook or US gov to ask why people leave facebook ?
These experiments are so subtle that you would not even notice they are being conducted.
You feed is manipulated to show you content that either make you angry, rage and on and on.
Beside, there are always some kind of campaigns going on. Male hate campaign, feminism campaign, black racism awareness campaign on and on. I mean come on, once in while getting some message is okay but 90 % of time peoples feed is filled with some campaign, message.
Plus, kids and dogs -- dont even get me started. Stupid kids everywhere.
Beside you can't block everybody and every message otherwise what's the purpose ? So its better to leave facebook. You should too. I guarantee you will feel more happiness. Try for a week.
and yes, please go shilling somewhere else.
