again, these are ads. not job postings, job ads. it's not "harmful" to enable advertisers to choose which audiences to target.
At least according to “Is It Discriminatory to Advertise Job Opportunities on Facebook?”, https://www.thatcherlaw.com/blog/2022/12/is-it-discriminator...
But it was posted, and apparently that's what matters. So the ads that signpost you to the posting that only [people with special glasses] can see are just peachy.
