No problem solved, no hack : became Master with +209
By dendicodeforces, 9 years ago, In English

This is the first time I write blog. Here's my story...

While I was looking at rating changes in Round 305 div 1 http://codeforces.com/contest/547/ratings , I've noticed contestant sheisactually14 who gained +209 but took place 631. I looked carefully in his profile and found something strange.

His contests tab :

http://codeforces.com/contests/with/sheisactually14

If you click to the number 177, his place, you will see :

http://codeforces.com/contest/547/standings/participant/4756047#p4756047

He gained +209, became Master but solved no problems and had no hacks. Can someone, I wish MikeMirzayanov, explain for me about this magic ? Or is there a bug in rating system ? Oh hell... What a myth actually !

Just look on his submissions. Treir verdict are 'Skipped'.

Perhaps, their verdict was changed after the user rating.

Submission is ignored becase of cheating? If it is right, why his rating remained increased?
