I see a lot of this sort of "misinformation" on eBay, from sellers who apparently are convinced that the only way anyone will see their ad is by putting in popular search terms. Maybe it's not the worst thing in the world, and maybe sometimes it's even useful; mostly, I tend to find it deceptive at best. (If I were looking for a TR3, I'd search TR3, or TR-3, or TR 3, and/or other variations; some sellers are smart enough to include common variations in their ad copy. Conversely, I tend to be annoyed when, for example, a search for a TR6 actually leads me to an ad for a TR3!)
