I know of a few players that changed their accounts due to them playing on FB.
FB does not allow, friend invites and creating tourneys.
They received the new accounts with some (choosing) to start from scratch
Others got re-instated at their current tier, which gave them what they had with the exception of losing all of their stats and restricted to cc play for a month
It was a choice that was made and certainly not without the risk of ridicule
Certain things happen on this site that does warrant a question or two, but it would a fair statement to say, get both sides of a situation first
Have a good one !!!
