A Spotify AdBlocker for Windows that works via DLL injection and function hooking.
The latest version can be downloaded here. The app is portable and there is no need for an installation.
BurntSushi works by intercepting network requests and blocking ones that match a set of filters. This is implemented by injecting a dynamic library into the Spotify process that overrides getaddrinfo from the Windows API and cef_urlrequest_create from libcef.
The status of the Spotify process is determined using wineventhook which is based on SetWinEventHook.
Theoretically yes, but practically it probably won't.
No, BurntSushi supports Windows only, but you can check out spotify-adblock instead.
