Equally pernicious are the Youtube "reviews" on the thousands of channels that profess in their title caption to be reviewing products A through Z. Pick any common product you have bought, from household items to hobby related merchandise, and you will most probably find overly enthusiastic endorsements. And most of those channels will not give the viewers a full disclosure regarding receiving products for free, or for a "small commission" on the sale of the items through a link under the title caption. Buyers beware, and aware (and weary).
