How irritating. I filed the DCMA complaints with Google, with their web page assuring me my "personal information" would not be shared on Chilling Effects. But I went into the SERPs today and found a nice big notice about two results having been removed, and how you could read the notice at Chilling Effects, and there's my full name at the top.
This is a problem because I blog under my real name on a totally different topic, and it's sort of a, well, branding issue. My real name is associated with expertise and experience in a particular field, and here I am also owning these totally different sorts of websites. It could confuse readers. This is exactly what I was hoping to avoid with HostGator.
Word to the wise: DCMA is intended only for businesses and lawyers. If a little guy wants to use it, be prepared to have to share at least your real name and maybe more.
From now on, I'm just doing the dupe content thing via Webmaster Tools and waiting patiently. Google always removes the dupes eventually. Geez.
