it's quite normal to come across newbies making very short posts especially in technical board and mining boards. For some I've noticed they are basically bitcoiners offline they just come here to find solutions when they have issues.
It's normal for people to create an account looking for a solution. It's not normal to create an account to
post "an answer", especially when there are many doing it within an hour.
Just to quench my curiosity. Are there people who use the forum by creating an account anytime they want to discuss in the forum. I mean they could be using a throwaway email to register each time they want to use the forum?
