Bests & Worsts Reviews from Amazon

I was looking to buy a calcium supplement and came across this product. Wanted to draw everyone's attention to the large number of clearly fake 5 star reviews by what seems one source. All reviews are titled "five stars" and all are just 2-3 word reviews similar in language with similar sounding reviewer names happening always on successive days. The reviews start again after a few days and same pattern repeats. Clearly an attempt to post fake reviews and increase the rating of this questionable product. For a medicinal item this is dangerous and unethical!!
