In my point of view, it kinda be really annoying for new people.
I have seen lots of new artists trying to have more recognition on this page but they leave when they discover the scouting system, getting a second wall for those new artists that are scouts is the same as saying that you have a vip pass to a club but you have to show your ID anyway.
yeah, there is a lot of people that doesn't follow the rules, that's why the whistle system exists but is kinda dangerous on how you don't know if mods are going to see your message.
And finally, is just too hard to gain attention from people even if you are an scout so using a blam/save system will just be stressful for the artist as you have to make something that the community thinks is acceptable, or even come through lots of bad rating just because that user doesn't like what he sees (like movies from new people getting a rating of 3 stars just because he is new and not for the content he gave).
