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 was able to delete one old account that posted in a disabled sub.
