he is not saying he doesn't want to do bookclubs he is saying he does not want to spend more time to do bookclubs than he previously did, it is not beyond the wit of man to efficiently pick out a genuine request, but even with efficiency time and effort required is not null.

If there is more slush and the fraudulent slush increases in quality and scope it must mean that the wit, effort and time required must also increase to deal with the problem.

Dealing with problems that do not give one a return on the investment seems not worth doing, especially when it turns out the most efficient way to deal with this particular problem is to absolutely refuse to do any book club stuff.
