If you do not actively go on the WTS section of MPGH then let me fill you in. In that section people sell stuff.
Player shops are the new thing everyone is doing, for example selling those bruteforced steam accounts, and usually the shops were centralized, they had the information of the multiple things they were selling.
Now this is going on, people make their shops then they make like 15 threads, each one advertising each of the things they sell.
This is irritating, I will show you a picture, it shows page 2 being dominated buy the same 2 people more or less
Also the thread makers decide to do their daily bump on each one at the same time in the day, so on their bump time and the hour or so after you will just get your face spammed with their stuff.
This causes situations, where if you say wanted to sell your own personal account, nothing big, if you post before their bump time then you could get bumped all the way to page 2 within the hour.
I say make a shop section on the marketplace, and also, a new rule saying that you may only have up to 2 active threads in each section of the marketplace, I think that is pretty fair.
