I wish there was a setting that would prevent selected blogs from being reblogged by other users. Personally I don’t reblog a lot of stuff because I believe in generating original content. I will only reblog something if it fits in the philosophy of my blog. There is some value in reblogging because of the traffic it generates but there is also a creepy aspect about re-posting something personal from another blogger. With a little imagination and creativity people can do amazing work.
