Not sure if the user know what he is doing based on the description. Could you elaborate and provide proof?

no proof but not full of red flags, so let's do some research.

20 pages on outpost, maxing at 21 hours.

Seeing sales around 2 keys, more commonly under

at least 1, possibly 2 went for an eerie key which is under 2 keys. other one was asking 3 keys and he accepted lower on another item, so who knows.

much more common, unsold at 2 keys:

I think this suggestion is high. 2 keys should be the high range, if anything.

upon on what I've seen around outpost, 1-2 keys maybe, 2-3 no way

I SEE WHAT YOU DID THERE ^_^
