I can help!!! It is really frustrating.This happens when you have exceeded the limit on the number of comments Medium lets you write in 24 hours. Effectively you have been sent to Medium jail. You can try emailing the helpdesk and telling them you are not a bot to get yourself back up and running. Sometimes logging out and back in can fix it. Otherwise you have to switch your computer off until the next 24 hour cycle begins. (Depends on your time zone). Hope that helps. A🙏💚
