[Development] Anonymous Access to codereview.qt-project.org Blocked

[Igor Khanin]

IMO permanently blocking anonymous access to Gerrit is far from ideal, it hurts the level of transparency of the project.

But this is a common problem for public Git forges, and many have seemed to mitigate the most of it by deploying a Proof of Work proxy like Anubis.

Perhaps this can be tried here too?

Best,
Igor
