PayRue is a decentralized exchange being powered by the technology of Ethereum. When it was in service it used to receive special attention to many of the tokens being supported there. Since there were many additions of ERC-20 tokens, the audience liked the platform and thought it was about to grow up. However, that never happened, and now there is a small community that can still have access to the page.
The main platform isn't working on all computers or servers. It just works for a small number of users depending on their geographical zone, but it is too difficult to know which one is the right, or how to contact other traders to check in more detail if the site is still rewarding.
Based on public declarations from official markets, this exchange is little known and it's better to keep away from it. Delete every saved access you have to their link to avoid being tented to enter the page through the use of a VPN. You can be involved in fraud if you continue, or you can even receive viruses on your computer by clicking on an unknown server.
NOTE: The last proof I gave to the platform was a little reliable. The site can't be found. It looks like it was deleted or abandoned.
