What are the rules on farming Trading Cards?

Guys/Steam

Has it been clarified whether it is ok to farm these new Trading Cards?

I visited the Steam Marketplace and was very surprised to see so many Trading Cards already available. I then Googled the subject of farming them and discovered loads of people just idle their games for the common drops - kinda like TF2 items.

The issue I see with this is that the Trading Cards then lose their value/worth. The related badges then lose their value/worth too. Just like the achievement cheats have damaged the worth of achievements. Those of us who gain these virtual-trinkets the right way appear to be the foolish ones ...

So, Trading Card farming is ok?
TF2 item idling is ok?
Achievement cheating, is ok?

Any views, or clarifications?
