Lol I have put over 100 things on the market at a time that were things such as hunter forces, orc forces, hunter relax's, a few quicksilver stuff and some more orc stuff. So I would not agree with it.
What I would say is that put a limit on what actually shows up on the page. So like you put 25 items on, they are the only 25 items to be shown on the first page, the next amount of items that are put on that hour will be pushed near the back. That way you can always put items on, but not all of them show up on page one. They are found by going back or searching for them
That would be much better.
