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 fully delete my account and I was the owner of a disabled sub. I migrated to a different sub and stopped posting in the old one and it was subsequently disabled. I had at least 30 submissions in the disabled sub. The last submission to my dead sub was probably a year ago.
