Anything that has value will be gamed.
It seems the only way to fight effectively is to automate the process. We can't hope to catch everything. Perhaps some kind of machine-learning process could help here to spot patterns with some human stewardship.
This will never go away completely, but perhaps it can be made marginal and largely ineffective as a strategy to extract value.
I agree with your view point. The process is going on recently...hope to see some progree.
