Everyone's noticed in the past few weeks that GB sales has been infested by users seemingly flexing their GB. This is because GB sales orders the listings by price, rather than by number, so any ridiculous number of GB will go right to the top of the list regardless of the intention behind it, just due to the cheap conversion they have. At one point, it was so bad, that the top seven listings were people "flexing" gb, ranging from just 100-30,000GB, with the highest now being at 34,000GB.

It's increasingly obvious that trades like in GB sales these are for the sole purpose of the users who put them up to go "look how much GB I have!", as these are not feasible trades. No one user has millions of SB laying around, and those that do have a ton of expendable SB don't tend to have more than 50,000 on hand at any given time. There are a few fixes that can be done to GB Sales **in Oasis** to prevent this, which are as follows:

1. Ban large bulk trades. I'll leave it up to the staff to decide what they actually do, but I would recommend anything above 100 as being considered a 'large' bulk trade and being banned.
2. Adjust GB Sales to show bulk trades at the bottom. List the sales by Number of GB and then order by price within that. For example, all trades with 1GB would come before any trade with 2GB, even if a 2GB trade has a cheaper per GB price. This keeps singular GB trades up top, which are by far the most popular. It can also be done by sorting by total list price, which does the same thing but may allow ultra cheap bulk trades to go above market-price bulk trades.

It's a bit obnoxious knowing these trades push the actual trades a bit lower, and it's especially noticeable on mobile, when these large trades can push actual good faith trades down even more. Nobody does these trades with the intention of just showing what they have, they want to be the center of attention or to knock someone else down a few pegs. While this definitely isn't an issue that's killing the site, and is relatively minor, I think it would just be a nice trend after all the recent QoL updates to help out GB Sales a bit.

Let me know if you no support, and the reason why! It'll help me make my suggestions better in the future.

Some nice points from the comments as well:
Mad Hyena - "Support, it is reasonable - trades have a limit of 100 individual items, GB sales should have a limit of 100 GB per a single listing. If a person wants to sell more, they can always create several 100 GB listings..."
ShakiraFuego - "...To your point for #2, instead of a sort within a sort they could also sort just by "Total List Price" instead of "Price per GB" that should by default bring the larger quantities further down. But I am fine with amount of GB too, then sorting by price, it just seems like an extra step."
