...If it's a beatiful girl "ohhh she gets the money because she's got boobs"
If it's someone with a steem-related concept, whether steem-cakes, steem-clothing, steem-photoshooting, "ohhh it's a circle jerk steem vote"
If it's someone who made a nice intro and got a lot of upvotes, "ohhh why should an intro get that much - I mean OK but why so much????"
If it's known people, celebrities etc "ohhh why would you vote these people that already have a lot of money while others are getting 10$ ?"
If it's people who do nothing of the above but got known for writing their stuff and creating an audience / following over the last weeks, "ohhh but they get all the votes and whale support - it's unfair for all the others!"
If it's people who provide stats, gem-lists, etc, "ohhh they just copy pasted the stats or a few links and got 500-1000$ - that's unfair"
If it's people who got upvoted for a comment, "ohhh why did you make 100-500-1000$ for just a comment? This can't be fair!"
...so for every case, there's always something to bitch about... But in the end of the day it's just plain "butthurt".
