You are right, and the behavior of your compatriots is very disappointing. But you could raise this issue in your local section. Besides the fact that your newcomers publish posts according to rule number one: low quality, providing copies and pastes with a link, this topic could even be located in the Bangladesh section. What is also noticeable is how your users grow accounts, thinking that the exchange of merit is not noticeable to others.
OP, do you have your own words or just a link to the news?
Looks like DVlog already addressed this issue in both global and local board. I see you have quoted some of his comment and found some low quality posters. Thank you for taking your valuable time to sort those users. This kind of things has happened before in BD thread. And I'm relieved that, many users have started to notice this. Because now this kind of activity will be stopped. As soon as a issue is addressed in global, users stops operating (Specifically in BD thread). The local thread will be calm, at least for now. With less and less copy paste source news and low quality translations.
