My theory is difficult to test but I want to believe that users unable to delete their accounts isn't from malicious intentions.
For those Phukers who have tried and failed at deleting their account; did you post or comment in disabled subverses?
My theory is that the deletion code can't run properly if you posted in subs that are now disabled.
Have no idea how a coder would fix that problem without reopening all the disabled subs.
I'm not sure, but it has been three years.
Then again, you may be on to something. I was just able to delete another account I forgot about over there that was older than my chmod account.
