It got so bad that I basically had to stop using Google image search for a while until I found that plugin also. It's made image search useful again.

I get that Pinterest has a dedicated userbase and get utility from it. But it's basically polluting search engines with spam at this point for non-users. I kind of don't get why it doesn't fall into the same problems that experts exchange did with showing google one thing and users a different thing for purposes of indexing. It resulted in them getting deprioritized and the main search working better as a result.
