PC Gaming

I never claimed that it never happened? A single well known example and also the only one you provided, from half a decade ago.

Yeah, no one at Valve, the same people that won't even make their games playable without a massive community uproar, is reviewing any of these. That being something which directly affects there reputation as a company and there bottom line through crates/keys, instead of there reputation as a storefront to publishers. The article even mentions Valve's addressesing this was a reaction to devs salivating over EGS having opt-in reviews, more so than them actually caring about publishers

Developers have cited this sort of toxicity as a reason they’re excited about the Epic Games Store, which plans to address the issue with an opt-in review system.

Also in the same article, they describe the option I've been referring to. You are still able to see the marked reviews reflected in scores if you wish.

On top of that, Steam users will be able to opt out of this new system entirely by using an option that’ll keep review bombs in games’ review scores. And, again, people will apparently still be able to look at reviews that have been removed. Review bombers won’t have as much power to affect games’ standing with the Steam algorithm, but this could also just encourage review bombers to find other ways to evolve their tactics and get through what sounds like some still worryingly large loopholes. Time will tell.

If you want to review bombs or "review bombs", you can still do so on Steam, and the score will reflect your preference for that, as opposed to EGS where you may not be able to see any reviews if a publisher doesn't want you to.
