I think he just loves a good ball washing. He's almost assuredly ranked up more useless spammers and shitposting alt accounts than any other single individual on this forum. It directly leads to a decline in the overall quality of the forum as visitors must wade through pages upon pages of ball-washing, merit-hunting, quota-fulfilling spam to find single nuggets of actually valuable information (which they're not going to do, BTW).
How hard is it to understand DCA? Every essence and nuance of it could be covered in 1 page with 20 (good) posts.
As far as I know, everyone on this forum has some freedom. Your choice and mine can never be the same. It is JJG's personal choice where to give merit or where to post. It's pointless to argue about it. What you came here for is unknown to all but you. But I don't think the discussion in this thread is worthless at all, and there's no reason to think so. Because, the problem of 5 years ago and the current problem are not the same, the solution of 5 years ago and the current solution are not the same. Newbies have new questions, the answers to those questions will not be the same as they were 5 years ago. Everything changes with time. So, 20 good quality posts on page 1 may be enough to learn about DCA methodology, but not enough to answer topical questions.
