How would you help Google curb the current sub-subdomain issue?

If you can, how would you eliminate the sub-subdomain issue...

Hello respected webmasters!

I'm just curious as to what you are thinking regarding this issue.
Who knows, Matt Cutts or GoogleGuy would hear our pleadings...

I know most of you knows about this issue but just for those who are new,
this is a current issue in Google wherein a site with so many subdomains
even those newly registered domains gets a higher ranking in Google.
This happens because Google treats each subdomain as a separate website.

I just learned about this issue last week and as of today, this still exists.

The current behavior of Google, treating the subdomain as a separate website
is very legitimate. This is specially so with some free hosting sites where
they offer a subdomain.maindomain.com.

For me, this could simply be eliminated by devaluing the links pointing from
a subdomain.maindomain.com to the maindomain.com...specially those
excessively doing this.

Hope to hear your thoughts on this.
