We've gotten a review on our listing that definitely violates HAQM guidelines, but we're not sure what else we can do to get HAQM's attention

The review in question is an obvious copy-paste because the same user also posted the same completely identical review on another item from a different seller on the exact same day. Even the typo in the review text was copied over. The title heading was also the same, with the substitution of a dollar sign in place of "money" on the second review (very clever dude...very subtle).

Both are bulk items, so it defies common sense that someone would buy both in good faith (no one could need that much), test them out, then coincidentally post identical reviews on the same day. The customer also hasn't responded to any outreach from us, nor have they requested a refund or returned the item, which is odd when the review complains about a "waste of money".

We've already sent a message to the community health email address we got from customer support, as well as filing a policy violation complaint (ID# 17842188951 if you're listening HAQM), but so far it's been radio silence ever since. What else can we do to get their attention?
