I swear like half of listings on warframe.market are just fake to manipulate the market. When I use it, I often run into:
a) outright fake ones:
- new accounts with no avatars, seemingly randomly generated or asian names, very little rep (not that it matters but you get it),
- marked as "online in-game", yet game says their nickname doesn't exist,
- they put up listings that would make no sense for a newer player such as vaulted parts,
- their prices are usually the lowest.
b) people who don't respond:
- they do not respond
until around 10 minutes have passed (15 mins is max according to rules),
- when they finally do respond, they claim to have already sold the item,
- I believe it's a mix of legit people who are just overwhelmed and fake listings.
Both of those seemingly aim to lower the prices on items, so they can buy them cheaper. I've seen asian names sell items in huge amounts and let's be honest, chinese aren't the type to play fair. In their culture cheating is acceptable as long as you get good results.
Look at this listing for Lavos Prime Set that I saw under "most recent orders" on front page:

Suspicious name, but it could still be legit. So let's type "/profile afsffs" to check:

And it was listed a minute ago. It's like this over and over and over. Few days ago I wanted to buy a certain prime part and guess what? I went through like 8 of the lowest listings via /profile command. NONE worked. This sort of stuff always happens when chinese are involved, I wish they were region locked out of the civilized world.
Riven market is probably even worse, but I only sell trash rivens for cheap and don't care if i lose a few plat. Can't be bothered to deal with this bullshit.
