These odds are still extremely slim. Even if there was one Pillowfort user who has heard of Wafrn, that one voice wouldn't be loud enough to reach the whole crowd in time before they all move to something that's nothing like Tumblr or Pillowfort (e.g. Mastodon, Bluesky). And I don't think that there are that many more people on Pillowfort who have heard of Wafrn. Especially considering how few people on Mastodon, much less Lemmy, have heard of it.
