There's an account on the Frostmourne server, under the name of, "Iliililliili" (I've double-checked that's the proper spelling) that is constantly placing dozens upon dozens of materials, consumables, etc. up on the Auction House for the minimum bid price (2 - 3 copper) with an unreasonably high ask price (far above what the standard market value is.
Whenever I've placed a fair bid on any of the items (enough that it's close to market value, but can still turn a slight profit) or any bid really, I find that within a few minutes I'm outbid on these items.
I can't fathom how else this is happening, and with a character name such as that it just seems obvious that they're using a bot to manipulate the market prices of items on the AH.
Is the Development Team going to do anything about this?
