How reliable is wiki auction tracker

[stewe]

I was just wondering how reliable the tracker on that site is, i was looking stuff up yesterday and i noticed the prices on that site were no where near the prices people were wanting for the same item in EC. Can people make alts and turn on their logs and put up fake auction prices then send those logs to wiki to raise prices for stuff they farm and lower prices for items they want to buy is my real question. Is the wiki prices reliable and do logs get put into the tracker even if the item doesnt sell for that price?
