When I try to search for "site:greasyfork.org guitar hero", it does not produce the desired result (the users' profile containing all of their userscripts). When I search on Google, the result is available. I realize that this is a bit nitpicky considering I can just click on one of the links and then navigate to the users' profile by clicking on their name on a particular script. However, the direct link to their profile is available when I perform the same query on Google.
Here is a link to the desired result:
