It's not bad for you, and it may mislead other buyers' shopping. Generally, buyers read reviews when they buy things. If the review is good, it will induce the buyer's purchasing psychology. This is the money that the seller bought the praise. Whether it hurts or benefits people depends on what you think. If the goods you buy are really good, you can certainly praise them objectively. If not, the goods are of poor quality and defective, which is seriously inconsistent with the description. I'm sure you won't praise them without conscience for the sake of praising cash. In addition, when we actually buy goods and confirm the receipt comments, it is not always 5 stars. The seller's move is to spend money to buy all your 5-star reviews.
