Glitch project removed?

Hi, I have made several Glitch projects with an anonymous account (without having signed up). The project looked live for 1 or 2 days, but today, maybe 2 weeks after, I click on the link and the project has suddenly disappear ! Can someone has the same problem ? Any way to get back to the project ?
Thank you

Unfortunately, projects on anonymous accounts get deleted after 5 days.


Yes. This is specified:

Projects created by anonymous users expire after 5 days (login to keep your projects around).
