You may not like it, but by definition, "Perl6" hobbyists are part of Perlmonks and part of the Perl community.
I do not welcome your attempts to cast them out of the Perl community in general and out of Perlmonks especially. I also ask you to reconsider your view that they are "freeloading", as they do put far less strain on this forum and whatever community than your incessant complaints about Perl 6 posts, which are mostly constrained to announcements anyway.
In 2016 that thing still called itself Perl 6. It hasn't done so in years.
(written by me back in 2016, the first part is still true and the second eventually happened) The only reason the Not-at-all-Perl 6 has so far put little strain on this forum is that next to no one uses the language, next to no one posts about it and next to no one cares. Therefore the number of posts that would be sure to confuse everyone with incompatible yet confusingly similar syntax is sufficiently small that they do not cause a problem. If the language ever gets followers and the number of posts grows we will end up with loads of "your code doesn't work for me, I get syntax errors" due to people running Perl code in For-God's-sake-rename-the-thing 6 and vice versa.
Even things that have been long established need to be reviewed from time to time.
