Being threatened with a ban goes way too far, but your question(s) as phrased does seem very much like sealioning even if that wasn't the intention, so I can see why a moderator might think it was. Obviously, they should have clarified first.

There’s been a large-ish influx of maga users, looking for people to harass in the last week as the other normies have left Twitter too because they are sad and lonely people, so people’s ban fingers especially those with large accounts, are a bit heavy right now. So yeah, it probably completely came off wrong (like someone asking when white history month is) vs asking if there was a specific other ethnic starter pack that drew your interest. Sorry that was your experience.
