Danny actually has a whitelist of people who wear paid signatures that do not post complete garbage. This pretty much addresses the issue of not being able to view constructive posts.
He does, however it isn't very conclusive. Members such as myself, mexxer and Lutpin are still blocked by Danny's list. I would consider all of us to have constructive posts.
I was removed from his list after I requested for him to review my posting history several months ago. He removed me from the ignore list and placed me on a special list on the next update. Seeing how he hasn't been updating it frequently, I doubt he is actively maintaining it anymore.
The spam wasn't this bad several months ago, I'm seeing threads with 20+ pages of spammers typing the same content over and over again. The worst part is some of the spammers aren't even talking about the topic itself.
