Google really should just comply with any validly formed DMCA request they're given, but put information links about that fact. (Which they do, to "chilling effects".)
And someone really needs to start tackling blatantly false requests too.
Google has already taken big steps to please copyright holders. Their detection stuff is remarkable.
Indeed. Rumor has it that American Airlines pilots have recently been engaging in a similar strategy in order to put pressure on AMR management. Apparently they simply follow the rulebook to the "t", phoning in maintenance requests for the most minor nit-picky problems, following every procedure in excruciating detail, etc., with a net result of causing American's "on time percentage" to drop precipitously as flights are routinely delayed.
The solution, not that likely to happen, would not be to write rules that you don't intend to budget the staff/time to actually follow as written.
