It seems like our gitea server was compromised. Well, not sure it was so much compromised as that I left login registration open and never set a robots.txt. So, people found the server, created hundres of thousands of accounts and started uploading repositories, mostly, it seems for spam. I blew away the repos, and started with a fresh install of gitea at the latest version and locked down registration. Now if you want an account you have to ask me or another admin.
