The base idea would be: As long as the author did not make it happen. It should be the authors pure intent to subject his/her post only to pure curation. To get upvoted by people, not bots and people who actually looked at the post before upvoting. I know its all a bit fuzzy as there, like in bodybuilding, will always be ways to cheat. Any better and more concise wordings are welcome.
What are your thoughts about the idea?
I think exactly that there will always be ways to cheat so my question was how you plan to deal with them :)
I would hope the #purecuration trending page would attract some scrutiny and the community could self-correct on a best effort, and that the consent to get flagged if caught would keep many away from trying to cheat.
I might write some visualisation scripts (like the flag-wars scripts on @pibarabot) if the tag catches on if I find these might help exposing specific types of trying to cheat, but mostly it should be a community thing of people agreeing to use the tag as intended and inviting flags if they end up, basically doing the equivalent of using steroids in preparation for an all natural bodybuilding competition.
