Nobody can make you do anything. You must take responsibility for your own actions in life. I can totally understand being pissed if you feel like you got the shaft b/c of a shitty review, but in the end, said blogger/youtuber did not grab you by the hand, make you buy a product and then keep it. In addition, perhaps the reviews might ACTUALLY be honest. We don't all like the same things. It is unfortunate that we don't all have access to brick and mortar stores, but you know what you are getting into with the reviews, obviously, or you wouldn't be posting/ranting about it here.
I am a makeup addict. That sounds stupid, I know. But, I have a SERIOUS problem with buying makeup and purchasing ANYTHING that someone states is even remotely decent. That being said, I could totally be pissed at quite a few people for "pushing their agendas on me". But, I'm an adult and the decisions I make, I own.
I'm sorry you feel this way and I'm sorry you feel you have had bad experiences with some bloggers/youtubers, but I don't think that this warrants any type of big ass retaliation from the general public to reform change regarding vbloggers. It is a free service, there is definitely "corruption" and it is what it is.
I hope you are able to find some reviewers that you respect. I really do. And, I hope this doesn't continue to plague you and that you can realize that those people who are actually being dickheads in the review process, aren't worth the words you wasting writing/talking about it. You deserve to be in better spirits than that.
Best of luck to you. I do understand, and I do hope you find what you need.
