Current behavior: We use HTMLParser to strip out all HTML, but turns out statuses can be rich formatted which explains why this exists in the first place. Some have funky formatting so there will be some weird edge cases likely if we leave the HTML in...
Proposed behavior: Just replace all twitter.com with nitter instance, in both text and html and see what happens

Seems to be a product of some crosspost bots, or this failed for some other reason
