Why are even adult women so obsessed with social media?
I get it. There's literally the psychological design, that the web developers have implemented. Those likes and shares and follows were designed to be addictive to keep it's users active for as long as possible and therefore those companies like Facebook and Google profit from selling user data to whoever asks for it.

Aren't adult women having more important matters on their minds such as education, career, work, skills, pursuing hobbies and interests, explore the world, cook/bake, be good at something, check their health with the doctors, fitness, cutting out toxic friends & family members and live independently from them?

Even adult women place such a huge importance on social media. We used to live just fine without any social media at all before around 2005. But I see, that adult women handle it the same way as do the teenage girls. When will women understand, that social media is not that super important in life?
It is no surprise to me, that women are pretty much naturally information gatherers but when someone like me protects their own privacy, then this man does not exist.

These women are the same women, who would rather sit at home on instagram instead of going out, talk or date.

I even heard of a confession of a girl I know. She said women tend to stalk guys on social media to get as much information about him (without his knowledge) as possible to form an image of what he is like and whether to associate with him. No data = he's not real.

Social media is cancer, a privacy nightmare and a source of depression.
They sometimes ask me to create an account on these platforms.
I sternly refuse it. I'm not into any of it. My private life is exactly that - it's private. I don't want it to be publicly available. I will tell women about me 1-on-1 when out on dates or via secure communication channels. But not on the publicly available internet.
