Greasy Fork is available in English.
Not even the people from Easylist seem to fight this site anymore, someone had to try as this looks popular enough. *sigh*
< Feedback on KissAnime Anti-Adblock Blocker
They are probably using Chrome with other weird blocking extensions.
The script is specially effective in Firefox, that's for sure.
Still works perfectly fine, not sure why it doesn't for other people
I just tested it again, and ran into no issues on kissanime. Script still works, as far as I can see.
Thanks for this awesome bit of awesomeness.
