Starting from today, whenever I try to submit my code, it shows “Sorry, you have been blocked”. I have tried these:↵
↵
1. Use an incognito window;↵
2. Turn on/off proxy;↵
3. Use Firefox/Chromium;↵
4. Use a fresh Chromium installation;↵
5. 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.
