Here is the two second low-down. Most stuff on pinterest is put there through links. You add a ‘pin’ to a board, usually through a link you have found. Now, here is how Pinterest makes money. They take the links, run them through a program and turn them into affilate links. Which means they make money every time you click. It’s ingenious and for the most part, unobtrustive advertising. [Here is a great post from blogworld about it].
In addition, there are TON of pins that are not linked to their original sources. Most people don’t care, but, there is always someone to cry about everything.
AND SOMEONE HAS GOTTEN A BIG UP THEIR ASS ABOUT IT.
Here is internet rule #3 – If you don’t want it stolen, copied, modified, changed then DON’T PUT IT ON THE INTERNET.
And for the love of all that is holy, stop pinning shit like this. No one cares.
