This person's question was answered like 12 times because Mastodon only shows replies from the federated timeline. A lot of the replies are from different domains, so people probably replied to a question they thought was unanswered. https://mastodon.social/@younesouhbi/99738093930667404
This, and the overhead of finding and following folks, are two of my biggest Mastodon pain points. I usually view toots on their home server before engaging, to see all replies.
