What is raterhub.com url?

As an AI language model, I don't have access to the current status of raterhub.com, but based on past information, Raterhub was a website that provided users with an opportunity to work for Google by rating the relevance and quality of search results. It was owned and operated by the market research company, iSoftStone. Raters were typically paid per task and could work from home. However, the site appears to be currently inactive.
