Yeah, I agree on all your points but this forum also has a lot of scammers pretending to be legit developers and sometimes we find this all too late, yet we are doing everything to get rid of these scammers, this is an independent forum and scams and questionable projects are not moderated everyone is given a chance to defend themselves, it's a fight between good and bad members.
I think this is outside the concerns of OP,Because scammers only victimized Noob and Greed that is the sad reality here
so counting them here is not appropriate because we are losing in scam as our own mistakes.
Look about my perspective ,I have often ask seniors here before making investment,once the coin get my attention?i make sure that some Good in investigation will take on it first before finally putting money,in this way at least i have small chance of being a victim?
Like what OP says,It is the Merit system that make this forum more cleaner,i wouldn't ask for more now because our Bitcointalk.org environment is now becoming one of the cleanest forum in all crypto sites.
