That thread was short-lived because the "member" turned out to be a registered spammer. Often a spammer posts a seemingly reasonable bit of information as prelude to a deluge of unwanted items.
Timeline: A new member joins and has instant ability to post. Sometimes "auto-mod" software flags the posts for review by a moderator. In this case it did not. One of the duties of a mod is to properly vet a new member through various databases. This member was a registered spammer and had posted a long-winded series of platitudes. Accordingly, they were banned and reported to the database to increase awareness. Hence, the entire thread was removed, as leaving the single response would lack context.
