How about anybody who has a REP score above 31 go inactive for one hour a day for a week?
That means no posts, comments, replies or upvotes for 60 Earth minutes.
Bots: They will remain active.
Scammers: Will do the same.
Plagiarists: 
Come on folks it is just one hour.
Do you think you are up to the challenge?
For the experiment to work we have to set a date and time.
When is best for you my good fellows?
