Dong U Dead - An item not being purchased at the price listed as the Grand Exchange median price isn't a scam.
Trade in the game is player driven - that is, a player is welcome to trade an item at whatever price they would like. If a player wants to trade a bronze sword, for example, for 100k, that isn't a scam. The player is unlikely to find someone who will participate in that trade, but it isn't a scam.
The same is true here with regards to the GE. As mentioned above, the GE lists the median price for the item being traded; this is updated daily based on the trade activity for that item. If no trades are occurring, then the item's price does not change.
If a player wishes to trade a certain item through the Grand Exchange at a price higher than the Grand Exchange median price, that is not a scam. If an item is only being bought at a price much higher than the Grand Exchange median price, that likely means it is an extremely low-volume item in terms of being sold on the GE and that it may be a better idea to search for other ways to obtain this item ingame. An item being sold at a price much different than the Grand Exchange's median price however, is not a scam, and there is no way or need to alert Jagex to these items.
