yeah, i edited my comment while you were replying to note that /g is a valid flag for m/// as well. it is a valid perl matching operation precisely as-is but it can't match anything due to the spaces it has before the ^ and after the $.

from the /g at the end i agree it looks like it could be a malformed attempt at an awk/perl/etc substitution operation, and your rewrite of it as an s/// does work, but the parts between the ^ and $ would also be a valid regexp in Perl-compatible regexp and some other dialects if not for the spaces at the start and end. And, the /g is also a flag ("Match globally, i.e., find all occurrences.") for the m/// matching operator in Perl.
The \1 and \2 are backreferences to the capture groups, which can be used not only in the replacement part but also in the pattern itself.
You can see this working by running this command:
echo '123 - 45 - 67890 45 123'|perl -ne 'print if m/^(\d{3}) - (\d{2}) - (\d{5}) \2 \1$/g'
...which will echo the string because it matches the pattern. (if you edit the input string to change, for instance, the last digit, it will no longer match and will output nothing.)
There is no input that can match the pattern as it is in the comic with the space before the ^ and after the $ however.
Interestingly backreferences are also supported by POSIX Basic Regular Expressions (BRE), but are not supported by POSIX Extended Regular Expressions (ERE). (Also the former requires you to escape parenthesis and curly braces for them to become meta characters, while the latter requires you to escape them if they're literals as Perl etc do. And neither of the POSIX flavors supports \d as a shortcut for [0-9].)
which music genres do you like?
Did you not read the post? OP clearly says:
I ran the numbers and I like every single music genre pretty much equally

every email provider lets you "keep your own private key" as long as you do encryption using the interoperable OpenPGP standard with software running on your own computer. many email providers will recommend that you do this and will even instruct you about how to (eg, the more reputable options in this thread such as migadu, mailbox.org, posteo, and even fastmail all have instructions for how to use some implementation of pgp to encrypt your email).
meanwhile any company selling non-standard "email encryption" (eg, proton and tuta) which is not pgp-compatible (or in the corporate world, s/mime is also a standard...) is in the snake oil business and should be boycotted regardless of which shitty youtubers they're sponsoring this week.

in the view on my user page, the two comments are the same as each other but still different from the post:

Fendit, refusing this meme:
who's Fendit?
Maybe some Tamarian from a novel, or maybe made up for an academic paper? The only search engine result i see for "Fendit, refusing the flame" is the paper Picard understanding Darmok: A Dataset and Model for Metaphor-Rich Translation in a Constructed Language which "assembles a Tamarian-English dictionary of utterances from the original episode and several follow-on novels".
(it seemed appropriate to respond to this meme with some apocryphal Tamarian.)
that may be true but you should consider that HR departments are notorious for failing to document complaints from members of socially-disadvantaged groups
