No. This is a bad idea because Nexus Mods simply does not have the number of support staff needed to deal with all the horrible negative reviews that would pop up overnight. 'Reviews' would simply offer a place for trolls to attack mod authors and other users of the site. How do I know? Because I've seen it, both on my own mod pages and the mod pages of other mod authors. The trolling will still exist, downvotes or no. Upvotes and downvotes don't deal with trolling behavior, they simply mask it, and ineffectively at that. And as anyone who has visited Reddit knows, 'thoughtful and helpful' isn't usually in the lexicon. As stated previously, this would not work because Nexus Mods does not have the support staff to deal with the deluge of reports that would come in. That's the reason mod authors have moderation control over their mod pages: Because Nexus Mods support staff simply can't handle the volume of attacks and trolling that goes on. This is not what would happen. Why? Because a large number of users have no clue what mod causes their crashes, bugs, etc., and will blame whatever mod they think is the problem. Any reviews coming from those users will be tainted at best and completely misinformed at worst.
