I do see your point. I apologize if you already knew this, but the top level comment was quoting a mandate for the production and supply chain, not consumers. There isn’t a standard for consumer complaints other than presumably not to maliciously tie up resources. As you noted, the agency triages consumer complaints. The comment you’re discussing did not allege such a complaint would be spurious and stuck to debating the applicability of the supply chain mandate to what happened, though I think they also thought it was a consumer guideline. Here’s more context for where the original quote came from:

“Every manufacturer, distributor, and retailer of a consumer product distributed in commerce who obtains information which reasonably supports the conclusion that its product creates an unreasonable risk of serious injury or death is required to notify the Commission immediately. 15 U.S.C. 2064(b)(3). The requirement that notification occur when a responsible party “obtains information which reasonably supports the conclusion that” its product creates an unreasonable risk of serious injury or death is intended to require firms to report even when no final determination of the risk is possible. Firms must carefully analyze the information they obtain to determine whether such information “reasonably supports” a determination that the product creates an unreasonable risk of serious injury or death. (See § 1115.12(f) for a discussion of the kinds of information that firms must study and evaluate to determine whether they have an obligation to report.) Firms that obtain information indicating that their products present an unreasonable risk of serious injury or death should not wait for such serious injury or death to actually occur before reporting.”
