<human>: Give me the gist of the text in a nutshell

My boyfriend [33M] and I [33F] dated for about 3.5 years, and we broke up for a year. We took some time to figure things out on our own, and we both agreed in July to give things another shot. It's been a few months now, and it's working out well. We've both grown a lot and it shows. I'm very happy.

There's just one problem: one of the women [46F] he dated while we were broken up felt very jilted by the fact that we got back together. They parted in May, but they were never exclusive (although I think she thought so). She accused him of seeing me while he was seeing her (he wasn't), and has taken to her Facebook page to wreak her revenge. 

She has publicly posted every single picture she took while they were together on her page. Every. Single. Thing. She posts updates proving that she's tracking him and knows what he's doing. She has discussions completely bashing me in the comments of some of these posts (although I've never met her). I have reason to believe she stalks me on social media, although I have never provoked her or anything. We both have her and her friends blocked on Facebook, which is the only social outlet we know of that she has.

He's taken all action that he can, but nothing has stopped her. He's contacted her directly, filed reports, spoken to authorities, etc. She won't relent.

I'm trying to be the classy one here, but I'm at the end of my rope. I'm tired of this person trying to get in between us when we have our own things to work through (unrelated to her; I mean, we did break up for a year, after all). She's been doing this since July. I trust that he's done what he can to curb this behavior, but now I'm sick of sitting idly by.

What can I do? Anything? Anything at all?
