Last August, I signed up for the [300iq online course](https://codeforces.com/blog/entry/118336), hoping to improve my sports programming skills. The course seemed promising at first, there was a group of ±20 people with from 1800 to 2400 ratings, but after completing two contests, Ildar (or someone who has access to his account) stopped responding to messages. ↵

Many of us felt abandoned and frustrated by the lack of support. What's more, 300iq asked $100 in cryptocurrency to enroll in this course, adding to the disappointment of the experience. We've been waiting almost for a year for his response, but he still doesn't ignore us. As I know he still sells his course, so be aware of codeforces' biggest scammer!
