There is a nasty group of Lawyers out on the web that are causing a bit of an uproar.  The group is called Righthaven and the issue is copyright trolling.

What they are doing is finding well distributed news articles and/or Blog posts that are widely read.  Then they aquire the copyright for this item and litigate the distributors of the content.

They don't just attack the content but try to get courts to seize the domain of the so called offender.

 The EFF will assist anyone that finds themselves on the wrong side of this underhanded legal practice.  

 They have also put together a legal page  for those of you that are interested.
