She was likely banned due to your actions as "white Knights" starting a pointless argument in her defence (that she didn't need or ask for)
Instead of guessing is there not a way to find out exactly why she was banned from the mod forums. As for example she may have been banned as she was a re-reg and thus this argument would become pointless then.
She said she had been in the business for 4 years previously before going independent, and she joined both here and other local forums within the first day of her setting up her AW profile so I am guessing she clearly knew about these places from when she worked elsewhere as its a hell of a luck chance for her to find both places so quick.
So could it have been she has double accounted?
