Hi - Couple of things .. First, the way some people have been abusing the rating system is to create multiple SCG accounts and then use each to rate their own items.  We've caught this, and have actually deleted many accounts that were used this way from the system. And, we're continuing to monitor this.

Second ... The idea was floated asking us to tie the comments to the ratings.  We think this is a good idea, but can't implement this right now.  However, we are going to be implementing a system with the next week or so whereby the username/screen name of the person who rates your uploads will be listed next to your uploads in your account.  Each listing will be a link to the rater's gallery.

I hope this helps.  We'll put it out there and learn experientially.
