How many accounts on Bitcointalk?
Personally I had another account which I used for 'testing'
the forum. It had maximum 10 activity and 0 merit points.
I never used that account since I created the main one
(this one).
The truth one, it does not make much sense to create several accounts, because remember that the IP address can be tracked and seeing two identical accounts ban you, and build a verified account with prestige is a long time to achieve it.
