Simple solution: human players prepared to share one non plagiarized original post or video on hive should be given an immediate advantage.
Proof of Brain.
A community of real players can easily sort through the posts and vote them up or down.
Lots more thought needed for this but this should be the beginnings of a sorting system.
Well, but of course then I could post something on HIVE as a human (to 'verify' myself) but nevertheless let my bot play on Splinterlands.
And to be clear: bots are nothing illegal on Splinterlands. They are allowed. I just question that they are beneficial for the ecosystem long term.
