Pinterest is a malignant tumor on the face of the Web that exists to trick people who are trying to search for images. Being rich off that would be worse that toiling in obscurity.
Uh - can you elaborate? I often search for images and sometimes from pinterest - but I don't find pinterest interfering with my searches when not using it.
The poster is likely referring to how Pinterest links now dominate Google image search results. Clicking on the Pinterest link takes you to the Pinterest website, and not the actual image source. Pinterest will often block you from viewing the page unless you sign in or create an account.
