Although other social media doesn’t have a reward mechanic built into it, you’re not taking away from other people by using it.

The main thing here is that, on a social network, content is king. If people quickly learn that they can game the system with terrible content plus bots it will - drive new users away as all they see is awful stuff riding high and draw away rewards from those who are actually putting the effort in.

It’s nice to think that the network is self-governing within its own mechanics, but if you take your hands off the wheel and start to drift off the road, you have to put them on it again and enforce a correction.
