And of course i don't see any benefits of merits
The shitposting platoon will never see (or reap) the benefits, and they will forever feel persecuted and discriminated against, and for as long as they're around, they'll keep making theads to voice their frustration--but they'll also never figure out that it's because they keep posting unintelligible garbage in spam threads that nobody is ever going to read. That's the uncomfortable truth.
I'd also like to reinforce something that Vod has said, which is that it's too early to tell whether the merit system is going to weed out shitposters and account farmers, or to what extent.
Everyone is still getting used to the system, but I do think these fools are going to realize the futility of just mindlessly shitposting, that bitcointalk ain't what it used to be. That'll take some time--maybe months, or even a year. It's too early to assess the benefits and waaay too early to declare failure.
