98% sure this is generic job spam
It has been deleted -- and they posted it in #jobs-non-clojure where it is "on-topic" for a company that uses Clojure but is posting a non-Clojure job.
looks like my mental model had a false positive!
@afoltzm No worries -- it def. did not belong in #jobs so you were right to highlight it.
FYI: they were absolutely a spammer -- they joined under multiple accounts and repeated that same job posting in multiple channels, even tho' they had acted as if it was a genuine mistake the first time.
