Cheaters are frustrating, but they seem to be an almost inevitable part of life, no matter where you turn. They are, in a sense, life's "users" who live by a "me first/me only" life philosophy, and they care not one tiny whether the "golden goose" they are taking advantage of keels over and dies tomorrow... because they'll just move on to the next goose.
It wasn't ten minutes ago I said to someone in a comment that people just keep proving me right so your self admission, though it should come as a shock, doesn't. The benefit of your words of wisdom outweigh any risk to myself, so carry on.
