Sorry, you got it wrong. These are not all one person accounts. My account name: suparigach. I am new to this thread. However, I know the rules of Bitcointalk fairly well. And I know what merit is. I live in Bangladesh and I saw from Bangla thread that merit is given to newcomers here. So I did the post.
If you know the rules fairly well you'd know quoting a whole post is kinda against the spirit if not the rules of the forum. Time will tell if I'm right or not.
