Nice challenge @Daan!
Unfortunately .. it's difficult to find anything on Trending that's not bot upvoted. That day I did a sample of a few $1k upvote posts and realised that they are 90% bot voted .. and one of them is a 100% copy and paste with a "Source: TheOriginalSourceURL"
It's a sad case but well that's how this economy work .. somehow .. just hope that the Steem team will fix this before it spin out of control and to the eventual demise of this amazing platform.
