[Plugin Request] Flags

Hi Aternos Team!, Could you please add this plugin?
Plugin name: Flags
Plugin download site: https://dev.bukkit.org/projects/flags
This plugins add more flags to the famous plugin for anti-grief and anti-spam Grief Prevention.. i use it because Residence plugin is very outdated and didnt worked on my 1.9 Bukkit server, i started using Grief Prevention and i love it, and i would like more flags so i can protect some more stuff.

Thanks!
