Although magic rank is fun, it's also sometimes confusing.
This script can be used for disabling magic rank. You need to install a browser plugin like Tampermonkey to use it.
But, it doesn't work if there are old handles which have been changed recently on the page (during the new year, there are many people who changed their handles, so in many pages, this script doesn't work), due to the CF API (the API won't redirect old handle to new handle, and the whole request fails on a single missing handle).
Last year someone made a userscript for the same purpose: https://codeforces.net/blog/entry/64131 (still seem to work now)
Instead of querying the Codeforces API, it downloads a file on GitHub which contains the rank of everyone (which may be faster or slower depends on Codeforces/GitHub connection speed), but will definitely not fail as long as the file is continuously updated)
