It's plenty of accounts unused, so don't worry about this
(there are also at least 300 accounts used in the past to spam on this board :evil: )
So I think also your account will be kept active (also for understanding issues, if another user will gain access to an already used account, all previous posts can be meant to be related to the new user, even if they are not, the only way to remove this misunderstanding issue is to delete all previous posts, but this way all the information provided by the former user will be lost...)
I'm almost sure that your account will never be deleted 8)
