Hello! I'm @dakeshi's supervisor.
While the tutorial may mostly be your own original work, quoting (copy-pasting, in this case) other sources without giving a clear source & permission to use these sources for monetization is a legal gray area for us. As such, we can't accept contributions that use sources that aren't fully quoted and under proper licenses.
Thank you for your response.
Could it be considered if I explain these constructs using my own words while taking your specification into consideration? I was in the belief that you can quote others, as long as you reference it.
Absolutely. I would gladly review your work again if that is the case.
Hello Sir, I contacted you on discord, kindly view my message there.
Thanks.
