It's reported in this article MySpace to Block Illegal Use of Copyrighted Music that MySpace.com is tightening its restrictions on users who post copyrighted music and video, including deleting the accounts of repeat offenders.
I am certainly in favor of strengthening copyright laws, which have been fairly lax online these past few years. And it's not just coming in a trickle; copyright support is appearing in a torrent and the most popular sites, including YouTube and MySpace are finally willing to risk losing users who violate copyright laws.
It will be interesting to watch the full impact of these decisions unfold in the next year or two as those who use and abuse copyrights face the consequences. Of course, it also spells opportunity for some enterprising individuals who operate within the existing laws!
