BTW I just want to point out again how little regard I feel Google/Blogspot has for copyrighted material (and that's why I think YouTube is trouble in the making for a lot of mainstream producers of creative works).

Sendspace will remove files the instant you submit a complaint to them. The process is automated.

Megaupload usually responds in very short orderl, as well. They also used to have an automated process in which the instant a complaint was sent, the referenced file would be deactivated.

Rapidshare would remove a file the instant their abuse department read the email, and would even make it a point to establish a dialogue with a regularly-complaining copyright owner so that you could easily submit complaints to them and get fast responses (at least that was my personal experience after getting passed their auto-replies).

Other hosting companies do the same.

Google/Blogspot? They'll sit on a DMCA complaint for weeks at a time. And could give a rat's ass if a particular blog operator has received upwards of dozens of complaints regarding their blog. They've made the conscious decision, I feel, that responding slowly and encouraging individuals to use their service, even if it means allowing them a great deal of freedom and flexibility to violate copyrights, is more important than ensuring people use the service lawfully and legally. They'd rather have 1,000,000 copyright-violating bloggers than 500,000 law-abiding bloggers.
