Starting from today, whenever I try to submit my code, it shows “Sorry, you have been blocked”. I have tried these:
- Use an incognito window;
- Turn on/off proxy;
- Use Firefox/Chromium;
- Use a fresh Chromium installation;
- Submit to another problem.
And while I cannot submit code, I am still able to access any other page (including posting this blog). Why this happens?
UPD: As a workaround, I switched to https://mirror.codeforces.com and it works.
