I agree.  At least it will stop the 'thumb bot' from keep clicking 'thumb down' just to push those they don't like down to the bottom of the rating.  It will at least cut down the number of manipulation because you must post a comment first to rate it.  As I observe, for example, the Chinese 50 cents, just a handful will write comment (in semi-decent English) but a lot more bots to suppress rating of the true Canadian opinion in the old system.  Quite a spectacle especially in the articles about Chinese buyers in the Vancouver real estate market.
