One cg points per download ?

I don't think so.

I'm pretty sure they did, and when I say they did, I never got one from a free download.

I had this model that I uploaded a few years back, it has 2.5K downloads and my reputation 580 something. So no I've never been awarded a point for my free model's download. Maybe for it's likes?

I think they removed it because I only get points for likes
