Papa pepper was posting about this earlier. It's a bit worrying as more and more users join the site; I'd hate Steemit to fill up with spam. It's really indicative of the shallowness, desperation and selfishness of society. We have to be the examples and create meaningful, heartfelt interactions, and hopefully others will see that it is a more rewarding way to behave than the types of comments you just listed.

Ironically, there are already a lot of these comments on this post hahaha...
