I think there should be a KYC verification system and mobile verification system present on bitcointalk.org ? KYC will surely help removing multiple account users from the forum and make forum much more clean. But many people will fear to reveal their information as they wont have security against their private info. The forum is not run by a single person or firm. It is a place where all the people contribute to it and is handled by administrator. Also we dont know about satoshi, the person who created BTC and this forum. So, my question is will you reveal your private info to such forum (site) with no security against it?
This is never going to happen and theymos has stated as such.
I think that the scoring system works well, but unfortunately there is one important shortcoming.
Merit groups are formed, which are exchanged in exchange for financial benefits. What if they cheat others. It is important that there is money, people cheat and it is sad that the administration "does not see" it.
The question is. What will all this decentralisation do for us? From blockchain to the Stone Age? ..
The number of people trading merit between themselves is probably exaggerated, but it's a very risky business because you risk exposing all your alts and when this sort of abuse is spotted negative trust is usually issued thus ruing all their accounts. If this is something you're prepared to do just to rank up then know that there are serious consequences that probably don't make it worth the risk.
