Should I?

So my fiancés ex girlfriend & her brother & his gf requested to follow my fiancé on Instagram just to be the nosey little fucks that they are, should I request them myself being that he denied them, & I'm pregnant, we have pictures & everything on my page. Should I or should I not? Just to bust their fucking bubbles, yeah it's petty but this isn't the first, her & her cousins use to dm me hella bullshit being the haters that they are. Should I just to leave her and them looking salty asf, basically giving them what they're looking for or just leave it alone? 😂😩😊
