Yes, these specific jammers do, but someone asked the general question "how to detect a jammer" and a sophisticated jammer will use no more power than is requires so as to avoid detection. Could it be that there are such devices and they are successful at avoiding detection? Likely not as at present no one cares if they are detected. But if they start getting hunted out things will change.
About spoofers, yes thay are not available on eBay. But I was thinking about military applications. Can you know when you are being spoofed?
