с SpigotMC автор не убирал плагин, его там забанили.
Слова автора из Дискорда "TAB plugin support" - TAB was removed from spigot because I got banned for putting a link to premium version (which was on mc-market because they took the premium spigot resource away from me last year) in the plugin description.
Кроме Гит-Хаба, ресурс размещён и на портале mc-market (Беслатный и Платный).
