(iv) Information reasonably sufficient to permit the service provider to contact the complaining party, such as an address, telephone number, and, if available, an electronic mail address at which the complaining party may be contacted.
There's a common belief that a complaining party has to dox themselves in order to file a proper DMCA takedown. I don't really see it. I'm sure there's plenty of case law that clarifies what "reasonably sufficient" means in this context, so maybe some court decided that the law is interpreted to mean that you have to provide a valid physical address. Just based on the law itself, though, it seems like just an email address might be sufficient contact information to satisfy this element. I don't really see any reason why a mailbox service address wouldn't be german
The funny thing is that while the person trying to take content down needs to provide "information... such as an address, telephone number... electronic mail address" the language for someone filing a counter notification reads differently:
To be effective under this subsection, a counter notification must be a written communication provided to the service provider’s designated agent that includes substantially the following...
(D)The subscriber’s name, address, and telephone number, and a statement that the subscriber consents to the jurisdiction...
I guess the idea here is to make it easier to sue someone for infringement but it doesn't really take into account that people would be filing false takedowns. So some nitwit filing spurious takedown notices doesn't have to surrender as much information as the person trying to respond to them. This became a factor when Alex Mauer started DMCAing everyone in the world and was so off the deep end that a lot of people on YT didn't want to bother counter-notifying because they wanted to avoid giving up personal info.
