I mean there should be like a limit or something, if you haven't posted in like 7 years, for example, they could give you some kind of warning. You could maybe either say: 1. Yes, delete my account, I don't want/need it anymore, 2. No, please keep my account, or 3. if they don't answer within 30 days (or more/less) then the account will be deleted. But, if PMC doesn't want to do this, they can change the username to something like InactiveUser_549859. Just some random numbers.
