- No responding from mobile devices. The poor response rate is just too high.
- The reader is quizzed on the the contents of the communication before they can respond (randomly generated quizzes might be amusing).
- The reader has to retype the original communication themselves before they can respond....
- Timeout value, if no responses that pass the above tests in a given time frame, whomever asked gets to complete the task with no input and nobody can change the outcome for ... a week or so and everyone has to live with it.
- Anyone who wants to change it after the timeout value better explain why they didn't ask before hand... no idea how this would work, yeah we're getting into the weeds here.
Of course, these are all unworkable in a modern business environment but man ... I can dream that some folks would who make demands or provide input at least put a minimum amount of effort into things before they throw their given wrench into the works.
