Do you think there will every be any legislation against...
 

these companies that buy and horde 1000's of domains and just leave SE's on their sites until they are able to sell it for a high markup?

It's really unfortunate that any remotely good site name that may not have any monetary value to those who want it, are owned by these companies.

No diff from buying and sitting on property - I hope not!
I hate gov. intervention.
