Games That Are Removed From Steam By Valve Now Have Their Community Items Unmarketable.

Valve has recently imposed a new rule regarding banned games on steam. Any game that was removed by valve will have their trading cards, emoticons and backgrounds unmarketable, meaning you won't be able to sell them on the community market anymore, they will only be tradable.
This will pretty much put a final nail in Digital Homicide's coffin. All of their games were removed from steam due to numerous controversial incidents they had with steam users in the past. Items have a 15% tax from selling them, 10% goes to the devs and 5% goes to valve. Even though they had their games banned on steam, Digital Homicide could still operate by giving away their games for free so people could farm and sell their trading cards.
Here are examples (not from digital homicide):

"This item can no longer be bought or sold on the Community Market because Valve no longer has a business relationship with the developer."
All banned games on steam will soon follow this process and all of their items will no longer be marketable, only tradable.
