I was talking to my gf on the phone yesterday and we sent stuff to each other via Instagram that we then fueled our conversation with - I wrote "send nudes" jokingly (I know she doesn't send any due to privacy concerns, just as myself), and the conversation shifted to a sexual tone, just as I had intended.

In the moment of the joke, she also reported the message, and today I got a warning. A couple minutes ago she asked me if Instagram had taken any action, to which I replied that the message got removed and I got a warned. She responded "I'm disappointed. Only a warning? After all, you're a dangerous sexual predator, aren't you?"

I can't come up with a witty reply to this. Any ideas?
