> So let me clarify what we mean by attribution. If you republish this content, we require that you:

> - Visually indicate that the content is from Stack Overflow, Meta Stack Overflow, Server Fault, or Super User in some way. It doesn’t have to be obnoxious; a discreet text blurb is fine.
> - Hyperlink directly to the original question on the source site (e.g., https://stackoverflow.com/questions/12345)
> - Show the author names for every question and answer
Hyperlink each author name directly back to their user profile page on the source site (e.g., https://stackoverflow.com/users/12345/username)

The site you mention follows each of these rules, and hence is giving attribution back - and hence as of now nothing needs to be done.
