hahahaha...
Do you have an option to alert people when you respond to their comments, or is she just frantically refreshing your page hour by hour to see if you reply?
Either way, run. Run as fast as you can.
No, no alert option set up.
I'm done with her, I let her have the last word then moved on with new posts about other things. I'm sure it's not the last I'll hear from her, but I know the next time won't be at my instigation, either. And I will just totally ignore in future.
Interestingly enough, I know another ENFP (male), who can't handle being blocked, either. He contacted an old friend of his, from whom he became estranged years ago, through Facebook. The guy gave him a chance, but it soon turned out they had nothing in common any more - the friend was now a married man with kids, bills to pay, a career and all this, whilst the ENFP was still roaming from pillar to post, freeloading off other people and without a job to his name in years; he got on the friend's nerves, and started trying to freeload off him, too. The friend sent him a tactful message saying that although he had thought it was nice to be back in touch to start with, he now realised that they'd both changed and moved on in their lives and had little in common any more, so he thought it best that they went their separate ways again. This was a year or two ago - the ENFP still rants about it to other people to this day, about how unfair and "c*ntish" (his word) he thinks the guy was for brushing him off. He reckons if you don't want to be his friend any more, you should just carry on tactfully declining his company with excuses forever and ever, to save his face, and doesn't agree that the guy's honest and up front method was honourable or fair. It's clear to anyone who hears him talking about it that it's FAR more about bruised ego at being let go, than any attachment he felt to this guy or sadness he felt at losing him.
He also believes, when he gets negative responses from people who know them both, that this is due to the other guy having "slagged him off" behind his back... the guy never mentions him, and even if you do, he changes the subject quickly without making any comment, and doesn't want to go into it!
I did say at the start by the way, in the OP, that I acknowledged this was more of a "crazy person" thing than an ENFP thing... but crazy ENFP's have a way of manifesting their craziness that's different to other types, still, wouldn't you say?
