We posted a review some time back (around 2007) and have recently received a DMCA notice via Webmaster Tools. It appears to have been filed by a company which does mass-DMCA notices as a service for whichever company has hired them.
We have even been in contact with and in cooperation with the company who's product we reviewed! The page contains a couple of photos which we made of the product and links back to the home page of that company.
6 days ago, we filed a counter-notification and have not heard back since (expect for an acknowledgement email from Google that they have received our request).
Now, here's where it gets weird: On an SERP where our homepage was last night, it is no longer to be found but instead the typical "we have removed 1 result(s) from this page". The page that should be ranking has no relevance to the bogus complaint.
As I understand it, Google will relist the page 7 days after they have notified the original complaining party and if there is no legal action taken, they will relist the page(s).
Question: Is there anything we can do to prevent these bogus claims and do DMCA requests have an effect on the entire site?
