Well you pay themfor their work. As a curie curator i couldnt tell you how many lines of text i could go through in 2 hours. Probably a 100 posts. And how many 50SBD or 100SBD bid bot payments do you think there are? Not many. You find those willing to do the work and give them a cut. Curators are payed by Curie and all Curie makes is from curation. Not a full blown business like upvote bots.
The problem is that there is no will. And wheres no will theres no action. Outside the coding im positive this could work.
