= Getting banned from Project Euler
{created=2025-10-02}
I have been banned from <Project Euler> for life, and cannot login to my previous account https://projecteuler.net/profile/cirosantilli.png
The ban happened within 12 hours of me publishing a solution to <Project Euler problem 961> https://github.com/lucky-bai/projecteuler-solutions/pull/94 which was one-shot by a free <GPT-5> account as <MathArena> had alerted me to being possible: https://matharena.ai/?comp=euler--euler&task=4&model=GPT-5+%28high%29&run=1
The problem leaderboard contains several people solved the problem within minutes of it being released, so almost certainly with an <LLM>.
I'm a huge believer in <Give answers to problem sets>[giving answers to problems], and I take the ban with pride.
It is funny to see that people waste their time policing this kind of useless stuff.
Project Euler likely has many fun problems, and can be a useful machine learning benchmark.
The "secret club" mentality is their only blemish, and incompatible with open science.
They should also make sure that LLMs don't one shot their future problems BEFORE publishing them!
