More recent Pro variant on the theme: You have a problem. You get a Google hit to a Reddit post. The top-voted Reddit comment has replies saying "That worked! Thanks!". But the comment with the answer is deleted, or replaced with boilerplate text protesting Reddit enshitification (and sometimes also advertising the automated tool to do this scorched-earth redaction yourself). Like both Reddit and the poster with the answer once at least partly understood the altruistic open-sharing global good that the Internet could be, but then they both forgot, or decided other things were more important to them. Fortunately, you can sometimes recover the answer from archive.org.
