Just when I wanted to try and figure out what the whole barrage of hacks was about in the last div3 I discovered this:

samin07 is hacking their own deliberately bogus submissions on their alt account olympiad2027... and it's obvious that samin07 thinks they will get rating points out of hacks, but they won't in a div3!

Seems like a silly way to out yourself as a cheat...

update: yes please keep downvoting me, I've got the third most downvoted comment in all of Codeforces and it's a badge of honour
