Maybe I was a bit unclear. The message, indeed, was from
Investigation@riaa.gov. And I rarely give out my email address to solicitors, so I think this is real.
EDIT: Indeed, at , I found this paragraph:
A great deal of copyrighted material is available on file sharing networks. Please be aware that many files are not legal to share or download. Please do not download LimeWire software if you intend to use it for illegal purposes.
But, if you follow the link, you will note that it is the equivilent of the proverbial fine print, if you catch my meaning. I believe that it should be more prominent on the site to help prevent illegal use.
But I'm getting way too off topic.
