I filed DMCAs for several Blogspot blogs that were hotlinking my images. Hotlinking seems to be ok according to Blogspot's (= Google property) policies.
This is the reply I got:
"At this time, Google has decided not to take action based on our policies concerning content removal. As always, we encourage you to resolve any disputes directly with the owner of the website in question."
Great, Google wants me to ask that thief in Vietnam, Indonesia or China politely to stop stealing my bandwith.
A great example of how Google is supporting thiefs.
Anyhow, I am now serving an ugly 1200x1200 pixels image with the name of my website to replace hotlinked images ...
