Eye on the blog - Lindens admit mistake over DMCA:

Responding to Questions about the DMCA Process

Linden Lab inadvertently disabled some inworld content this past weekend.
The problem should be fixed now, and we apologize for the inconvenience it caused. If you believe your content was inadvertently disabled, please try re-rezzing it.
If that doesn’t work, please contact Support at http://secondlife.com/support.

Linden Lab has not changed its DMCA policy. For privacy reasons, we don’t discuss the specifics of DMCA notifications with third parties. However, when we receive a valid DMCA notification, we send affected Residents email notice so they aren’t surprised when we remove content from their inventory and inworld locations.
The email notice explains how to submit a DMCA counter-notification to seek restoration of the removed content. Be sure to keep your email address current and make lindenlab.com an exception in your spam filter so you receive notices from Linden Lab.

We’ve received questions about removing infringing items from Residents’ inventory when an inworld location (a region name and coordinates) can’t be provided.
Inventory items may be subject to DMCA claims when the items are sufficiently identified. For example, if you can’t provide an inworld location, provide the names of the allegedly infringing items and avatars.

Linden Lab will conduct a reasonable search for the identified items.

Also be aware that persons who materially misrepresent copyright infringement in DMCA claims may be liable for damages, including attorneys’ fees and costs.
In one case, a company that sought removal of content protected by the fair use doctrine paid over $100,000 USD.
For more on this, see here.
If you’re unsure whether certain content infringes your copyright, we suggest speaking to an attorney before submitting a DMCA claim.
More information about Linden Lab’s DMCA process can be found on our DMCA policy page and in our recent blog post on Protecting Your Copyrighted Content.

Linden Lab’s DMCA policy has not changed, and this information is up-to-date.
