• Can't "incite interference with the election process"
• Can't suggest the election isn't fair
• Can't go against mainstream COVID-19 advice

• Retweets can have comments added to them
• No more suggested recommendations from people you don't follow
• No more suggested accounts to follow based on "likes"
