Why dont people vote back up the people that upvoted them

I keep seeing this lying stories of a Truck Driver, that bitch that is in tahiti this fake african guy that says he lifes of 1$ a day and some other posts that were well over 6.000$

But i see that those people dont even vote back the ones that upvoted them.

I mean you just earned more than 6-8000$ on your stupid post but you cant upvote back??

Fuck you, fuck all off you

Lets bring justice back to this wired steemit system and lets downvote trending posts!!
