Final breach of image guidelines?

I received an email today titled "final breach of image guidelines" saying I continued to violate a policy. But I'm puzzled by this, as I don't belive I've submitted anything that was declined recently. And I've been careful to avoid submitting images that have nudity. Can someone check this to tell me what it is for? I don't think I should be blocked from submitting anything.

There was a submission I made semi-recently that was initially declined, but I posted about it here, and was told it was okay and then it was resubmitted and approved. If that's it, I don't think that should be held against me.

Post regarding that here:
