Bluesky's users are in pretty much open revolt after it was revealed it was possible to create usernames with the n-word (and other slurs) in it; something that any project leads or development teams with any clue would have prevented from day 1 (there's easily available lists of "bad words").
There was a brief "it's fixed" statement (but they actually only did partially) and no apology; all the company and personal accounts of the Bluesky team have gone silent for ~2 days now.
