You base a date on someones account as a symbol of knowledge or trust?
I think you misinterpret slightly. The real issue is that there is no basis for trust. Nobody knows the guy, he can't prove anything he has said. Scammers and liars will always claim to not be scammers and liars so that means nothing. To have any value, you need verifiable sources to authenticate these types of claims, preferably multiple ones that can be cross checked for discrepancies and contradictions. Instead there are none at all.
It's a shame though, that many people are naturally trusting and if some anonymous account on a forum says that he mined bytecoin in 2012, a few people will probably believe it, and throw a a little money at a "good" project. That's why these scams persist.
You hijack a thread for what reason?
There was no hijack here. THE THREAD WAS ABOUT THE BCN NINJAMINE.
