An inflated ratio (uncool) occurs when a responder to OP uses uncool methods to "inflate" the perceived agreeableness or sheer genius of their response. Bot upvotes and bot comments are definitely dark practice, as was commonly accepted even before the advent of ratios.
The interesting part is the brigader in this situation. The brigader thinks he's doing the right thing and 'winning the ratio' when he summons his internet allies and real-life family (🤣) to upvote his response to OP. As Oogway once said about a small and independent pizzeria run by a single-mother of four, "Fajita and Pepperoni cannot go together." Maybe it was Gandhi who said it originally, but that's beyond the scope of this discussion. The brigader is wrong. There is no difference, in essence, between brigading for upvotes and bot-voting. Just the fact that the responses are 'human' does not justify the murder.
One might ask, "What if the responders perfectly understand OP and then disagree with it? Aren't they allowed to express themselves? And can that not lead to an organic ratio?"
No.
Take, for example, a political lefty community. If a lost anon finds his way to this lefty community and comments an extremely disagreeable opinion on a post, then links his 'based' response to 4chan and other anons upvote it and agree with,
would it count as an organic ratio? It's not possible for it to.
The audience that responded in the negative (to OP), is not even part of the community.
The "successful" ratio doesn't represent the opposition to OP in the given community, it represents an anomaly. The ratio is useless and OP knows that the community doesn't hold the same ideas as the anomalistic opposition.
Again, the forced-through-brigade ratio is no different than spambot ratios. They're both just as unrepresentative of the views of the community.
