Some of the ones that are obvious beginner games that aren't really polished have their place in EA/ex-GL, with people actually passionate about it and trying to build a product. Kudos to them for trying and good luck. This is a great thing, provides visibility for these creative minds, and all that.
This publisher deserves to be removed from Steam completely. It is not beneficial to the platform or to the players, and would probably cause increased refund request support load / chargeback or dispute load.
I more or less agree. I feel as if Steam is starting to look like the Android app store. It's at the point where legit games have to worry about SEO. That being said I think it's really hard to define super simple games that deserve a place to be seen and played vs. super simple copies and exploits.
They have for a while now. If you've played for less than two hours, and aren't requesting multiple refunds in a short period, it's automated now AFAIK.
