Omi mods handle account problems, but sadly different forums have different mods assigned to them, but since omi mods are in charge of account issues, just browse the list of forum mods and find one that is on and PM them.
Every time I am getting harassed and PM a mod they tell me that filing a report is faster even though I get a PM a month or two later about it taken care of, whereas when I PM a mod directly it gets taken care of within a few days.
