I'm more active on Ask Ubuntu and normally refer Kali users to U&L by telling them:
We're sorry, but this site is all about Ubuntu and its official derivatives as posted on https://wiki.ubuntu.com/Releases so Kali is off-topic here as well. However, on Unix&Linux, a sister site to Ask Ubuntu, they're very good at all varieties of Linux and Unix, especially if you use the Kali-Linux tag. ;-)
Should I stop referring them here and just post:
We're sorry, but this site is all about Ubuntu and its official derivatives as posted on https://wiki.ubuntu.com/Releases so Kali is off-topic here as well.
or continue doing the first one?
