There's nothing strange about that either - Twitter only acts to moderate when it has context and/or gets bad press. It's no surprise that American hot-button issues are the most moderated[1] by Twitter, and less sor for heinous, explicit threats to life in a language spoken by < 1 million speakers halfway around the world, or election misinformation in Kenya. That sort of thing never gets on Twitter's radar, and shouldn't come as a surprise.

1. This is a result of resource constraints, and Twitter's own sense of self-preservation. There is only one jurisdiction that can dissolve Twitter, and is also likely its largest revenue source; naturally, that gets an outsized fraction of Twitter's limited engineer-hours and moderator-hours.
