"Our competitor has accused us of using the heads of Venezuelan children in our product. These are the receipts from our suppliers in France proving all our meat is sourced from Morocco" and so on. Stick purely to response in the first post.
Then, in a later post, explain how the competition is guilty of all the accusations they've thrown at you, and worse: "Their product is actually made of sawdust with plastic skulls and inferior spices"
Don't sweat it if you are confident in your product.
They played themselves with these claims.
If they consistently rank themselves and others in the same bucket, but no clear winner, just you as clear outliers, you stand out.
Any potential lead/ user worth their need in money will want to check you out either out of curiosity or to benchmark their product eval better.
Better to stand out if you have no downside to be afraid of on your end.
