In my 1½ year here, I don't think I've ever seen the tag kali-linux-tools used correctly. People usually use this tag when asking about Kali Linux, which will then be closed. And there already is a tag katoolin for the script that helps install Kali Tools on Ubuntu.
In my opinion, this tag adds more confusion than it solves, so removing/blocking it would probably help with new users not using it correctly.
Also, the description is pretty vague: "Kali Linux Tools can be a synonym for Katoolin ...". But what else can it be? The options for misuse are endless...
