to be considered as a 'scientific journal' you have to maintain every post on it and it has to comply with specific rules ,that's not the case here .
this forum is more like a community that assemble people who are interested in blockchain technology in general .you can't force anyone to make wuality posts that's why moderators make "merit system".
Well, Bitcointalk is now used by many bitcoin users to earn money. There are lots of signature and bounty campaigns that ables the users and the members to have bitcoins and altcoins by posting and answering questions and opinions here in the forum. Bitcointalk is not lost, it is still alive. Just calm down and have a rest.
