Of course you can :)
For example:
Rob is a whale over here.He made it,thanks to his great posts,which he was doing constantly.
Now,he gives a lot of attention and money with only one upvote.Rob hates bad people.
Rob upvotes posts,where he can find out that person writing it was kind- that person was doing his posts (even with big effort and no attention given by other people) without complaining.
This kind of people needs upvoting,help.These one,who are hardworking and not complaining,doing quality posts at the same time.
Steemit is people.We control this network,so we should decide who needs to get out from here,to upgrade our community,and move along.
Nice! This is a really encouraging statement!
