Hi Joe, we are Jaguar Force, one of the main cleaning initiatives of the platform, we detect plagiarism and provide abuse intelligence to curators.
You can check our intro here: https://steemit.com/introduceyourself/@jaguar.force/introducing-jaguar-force

We could also help you run a background on the people to be added so you dont end up adding known abusers, spammers, plagiarists and the like.
Regards.
