pure speculation but i bet it’s somehow because it contains links to copyrighted/illegal content (to block it) lmao
I'm actually shocked that Github didn't have Adguard white-listed to prevent this from being picked up by malware scanning tools already. And it's a shame, because the whole point of scanning for malware is to protect people from falling victim to new attacks, and killing the filter repository is entirely counter to that goal.
PS: could not check the link, as my country blocked twitter.
* I often put malware samples in my repositories on github (I prepare malware analysis trainings, and I develop my trainings on github). Never got banned.
* There are a ton of leaked malware sources (and/or binaries) stored on github. They are not banned
* Github is full of blatantly obvious malware (at best "pentesting tools", at worst "educational projects"). Sadly, not banned too.
