I think that creates just more work for mods. My suggestion was based on trying to help mods out a bit, not cause more trouble :D
They already have to come in here and go through all the posts. They would have to process more aliases with direct submission, of course, but it'd be a streamlined process. Limiting it to high-points users would keep it from being too crazy.
At any rate, there must be a better solution than the current one. It's not great for users or mods right now.
