When I said "review" I don't mean praises, what I actually mean is; those reviews that are criticizing the app. Because you won't expect a company to pay people to comment shit review on their app but they could do it for some nice comments. Most negative feedback on play store apps were actually made by those who have used the app and found out that the app is shitty or maybe the app contain some bugs that they company has decide to pay deaf ear to. And besides the type of app that Op is talking about should have so many reviews trashing them because alot of those who have wasted their time on the app wouldn't want to just let their time waste for nothing without them retaliating.
