I see a bunch of suspicious reviews on a given game (two users with exactly the same display name and similar review counts, a series of short reviews saying more or less the same thing or missing the point about the game completely, and always positive), and I'd like to quickly report each of them as suspicious. But there is no such button.

Instead, I need to go to each user profile and report user as "Scammer, Hijacker or Phisher" following https://steamhost.cn/help_steampowered_com/en/faqs/view/4D07-D139-587C-2080 but that's a bit different, isn't it?

On some thread someone suggested to report the game, but 1. there is no adequate category for "hiring people to post fake reviews" and 2. we don't really know if the devs really hired people/bots to post fake reviews... there could be wild bots too (although there is no financial advantage to this). It also prevents me from pointing at the most suspicious reviews.

So if there is really no way, I would suggest to add a button to quickly report a suspicious review. No time wasted, and we count on many people flagging them to have the report go up and be verified by humans. And since fake positive reviews are pushing games higher in the list by the recommendation algorithm, it would organically bring more people to see them and flag them (while fake negative reviews wouldn't be seen a lot by users, but there the devs themselves will be really concerned and will not miss to report them).
