What I worry about is that certain whales will have lots of minnow accounts, upvote them all for crap, then milk steem for all it's worth.
There have also been some high profile bloggers here I've seen that have some really bad articles alongside their good stuff. In bad english. So i think they have hired a writer from Asia for pennies then posted it here knowing that theyll be auto upvoted.
Good investigation.
Curation bots only work if you have an actual brain behind the trigger.
Even the best code isn't capable of telling i an article is complete shit or not.. You need to read and understand an article before you can cast proper judgement.. Code can't exactly do that (yet)
