@pennypenguin People shouting for the rich to be murdered has at no point been okay, and again, content like that is moderated when we either see if on the timelines ourselves or when it's reported to us.
If you feel so strongly about the way your content was moderated, I'd encourage you either find another server, or head back to Twitter. We've been very reasonable in simply deleting the posts rather than limiting or suspending your account for breaking multiple rules in a short period.
