RJnomore no they don't contact you. When I was banned they didn't tell me they were doing it, they just did it.
To their credit though HQ were quick to reply to my e-mail after I mailed them to ask why and once they realised it was a misunderstanding they immediately reinstated my account.
If she doesn't know why she's been banned she should drop them a line.
FWIW I don't think I've ever seen anything from her that would be ban worthy.
