I would like to clarify that uploads are paused due to server/host changes. Despite the login request appearing, when trying to upload, it is simply because the uploads are suspended. You will not need to create an account when the service resumes 100%. Everything will continue to work, as it has worked until now.
Experienced users are aware of this. To avoid further activities on the site by trying to send requests to the server, it will be nice to hide the "Start uploading" button for now. By this, the pause in uploads warning be effective.
You are right! I updated the information.
With so much going on, I ended up not adjusting this situation correctly.
