I just did an extremely lazy version of that and posted a reply of "And the SHA-1 digest (in hex) of this tweet starts BEEF" - https://twitter.com/cooperx86/status/1701261047917633846 https://twitter.com/cooperx86/status/1701261047917633846 Basically I had several substitutions around words, case, punctuation, etc. and just ran it until it found some hits.
