Why my account is banned

Why is my account @shymp4ck blocked? I’m sorry, I don’t feel like I’ve done anything wrong and I don’t feel like I’m cheating, at that time I submitted the ngrx project before I understood how to make a tea project and that was a long time ago, even a long time ago, after that I only understood how to make a tea project, why did you get banned? my account now? are you fair? If I was guilty a long time ago you could have banned me at that time but why are you banning me now? Please explain ! My struggle to create a project was in vain

Previously, I didn’t understand how to create a project. Someone told me to be a contributor on someone else’s GitHub and I tried it there and couldn’t, I asked others and the result was that I could create my own project but why did you ban my account?
