I appreciate your efforts, @akukamaruzzaman, my friend!
as you, native speakers, inform and educate him in your native language about the common policy on Hive, this should be helpful and waht is needed.
also, what is needed, is that he would listen you, educate himself, put 2+2 , and improve his posting pattern/habits.
I agree with all what you have wrote. !ENGAGE 20 - cheers.
