Come across another few thousand edits of copy and paste violations again today. These have occurred over more than a year. It is wearing me out. Really what is the point on collaborating on Wikipedia if it is simply a copyright violation. We need a solution and one has been proposed here a couple of years ago https://en.wikipedia.org/wiki/Wikipedia:Turnitin
We now need programmers to carry it out. The Wiki Education Foundation has expressed interest. We will need support from the foundation as this software will likely need to mesh closely with edits as they come in. I am willing to offer $5,000 dollars Canadian (almost the same as American) for a working solution that tags potential copyright issues in near real time with a greater than 90% accuracy. It is to function on at least all medical and pharmacology articles but I would not complain if it worked on all of Wikipedia. The WMF is free to apply.
