When a rat detects something, how do you know if it's tuberculosis or a landmine? Do rats have different words or signs for each?

That reminds me of the Ferengi rules of acquisition:

34. War is good for business.

35. Peace is good for business.

Similarly, both recessions and economic growth are good for wealthy people who can take advantage of them.

Besides the merchant name, you also know how approx. long ago they launched (by how long ago your camels first saw their name), approx. how many items they have for sale, and how their prices compare to other merchants. Comparing that information between fake and real sellers, it seems like it may be possible to guess, up to a certain confidence level, whether a merchant is a fake. Also, you could try frequency analysis on the seller's name to train your camels to spot scammers.

Not if you film it.
