Well if you are Yahoo! you may define it as someone complaining when they get ripped off! Yes, that's right, you heard me, if you get ripped off and then complain about it on a Yahoo! site, then Yahoo! may claim you are harassing the rip-off merchant and actually remove your post!
Unbelievable but true. Rebekka Guðleifsdóttira (a talented photo artist from Iceland) found out that the rip-off merchants at only-dreemin were stealing her photographs. According to Thomas Hawk, she then wrote about it on her Flickr photostream, that post received much support from the community, but not from yahoo!, who claimed she was harassing only-dreemin and deleted her post!
Wow, way to support a community guys!
