You could remove one-word reviews, but then you'll also remove the ability for people to express themselves.
That doesn´t matters much as we are on the Internet and the so called "Freedom Of Speech" already died approx. ten years ago with things on forums actually getting so out of hand that even for just telling your honest opinion could make others tend to accuse you of being a "Troll" coz you have the guts to not get in line with the rest of the forum-hivemind...like for example:
User-A: "#1 is my opinion!"
User-B: "#1 is wrong! #2 is right!"
User-A: "#1 is still my opinion and you have to live with it for the rest of your life!"
User-C: "User-B is right with #2 and User-A is wrong with #1!"
User-A: "User-B and User-C are just butthurt, while being totally wrong with #2 and me being right with #1!"
User-B: "Don´t feed the Troll! Can someone ban this user please?"
User-C: "Close this Thread as well, it´s just Troll-Bait!"
I am online since 56-modem times and think i´ve seen "Freedom Of Speech" actually fading away so slowly and "unnoticed" that people already accepted it without even being aware of it.
There are countless numbers of examples i could tell how "Freedom Of Speech" is practically non-existent anymore, in countless forums and even if this is actually one of the far better and way more "grown-up" forums i visited within the last years, you also notice how people aren´t allowed to really say what they want, regardless of their age and the approx. age of the rest of the users here and also regardless of any possible policital stance they are have.
But this is all "normal", i am not ranting anymore as i´ve already accepted that sad fact like everyone else.
What makes the opinion of an official reviewer any different to a user?
There are good reviews from official reviewers as there are bad ones.
There are good reviews from users as there are bada ones.
But then again you have way more bad user-reviews than you have bad official-reviewers reviews...and you especially have way more infantile-toxic-braindead user-reviews.
If someone is forcing me to trust a review, then i wouldn´t hesitate to trust the one from an official gamer mag rather than some user begging for attention with this user-review on steam.
But then again...i am actually not trusting any reviews at all, that doesn´t mean i wouldn´t read them.
By the way, in my teen-age, when there wasn´t any internet, i bought all them magazines, reading and studying each and everyone of them reviews, but then again there weren´t so many titles to pick from, so as a matter of fact, i basically was buying ALL of the games being released per month mostly anyway.
