Unfortunately, bots are turning into a business on Steemit.com
If bots are eliminated, business declines, usership declines.
The question comes down to how to find a balance.
Heres a quick idea:
If a "bot vote" could be reliably differentiated from a "human vote", then an algorithm could be applied allowing the reciever of the votes to only benefit from up to a fixed percentage (say 10% value from bots, 90% value from humans)
Bots are a slippery slope at best, but I'm sure my dad said the same thing when programming UNIVAC.
...find balance while minimizing abuse is going to be tough..
