About at GameStrafe
This site is part of the GameStrafe network. As you can see there are not ads or other annoying things, just content. That's because every page is publicly available, each in it's own [github repo](). That means not only can you see how all this is made, you can also edit and add things (by submitting merge requests).
If you are interested in helping out or found a bug or something wrong, look at the contributing page for details on how you can do that.
