what i did was check my old emails typed photobucket in filter and found out what email i used that way cuz the email i used to sign up got spammed by them. without the email support wont help. if you no longer have access to the email they will still want to know the email registered to account you wish to recover
I did this, and found old links.
Have a email from 2013 with my user account on photobucket.
So I know I have the username right, they're jus not sending me the email 12 years later now when i request the reset.
