hI had 3 hubs stolen in 2 1/2 years. I filed a DMCA complaint and those sites were taken down.
Just in the last two days, I've had 3 other hubs stolen. It's distressing to see that not only the content, but the formatting, photographs and even the ads were reproduced. I did have a copyright notice within one hub and that was reprinted too! I will be doing a DMCA report on them.
Unfortunately, hubpages never takes off the red copyright infringement notice from my statistics even after the stolen content is taken down. That is frustrating also.
