So how many accounts do you have? You say you created 3 accounts, 2 were deleted, then you logged into an old account and then logged into your 'main' account. Doesn't surprise me that you have been locked. MA will probably want to investigate all of the accounts you have (past & present), what activity you had on them, etc to make sure nothing odd went on. You could be locked for a while depending on how many logs they have to go through.
