Specific word for social app user?

I am looking for a specific word to describe people who are active on social media apps: FB, Whatsapp, etc.

The nearest word that I found while searching online is netizen. Cambridge Dictionary describes it as:

a person who uses the internet

But, it does not fit the idea I want to represent:

______ are human beings without four limbs. They demand and demand, but can’t act in real life.
