A restriction of a newbie like myself is to prevent spam of boards but also of someone just creating manipulative accounts. Of course there are probably some people with 10 or 20 accounts on here that are used just to help them con other people. "My name is jimmy and what this guy says is right. You should invest in his scheme .eerrr plan." Barriers of entry are made as a form of filtration this is not always a bad thing.
That is obvious, but why should that cost be necessarily paid in posts and time? We have a wonderful measure of value here that is transferable. It's called Bitcoin. Why not just use it the way it was meant to be used?
