Why would former friend block me, then unblock, then block again?

Anonymous
My work colleagues spread lies about me having feeling (and other lies) for another work colleague/friend and she ended friendship,
Eventually the bullies that spread the lies about me and her then made sone false accusations to get me fired, it worked,

About 6 months after I was gone she randomly blocks me a FB, but not on IG,
I wasn't bothering her and thought it was weird but put it down to her friend telling her what to do?
Another 6 months later I get a job in the same building with a different company and about a month after I noticed she's appearing in my recommended friend list again (that's how I know she blocked me originally, because when she disappeared I checked)

So she's unblocked me, another year passes and we don't speak, I take avoiding action Everytime I see her and keep my distance, Nd I notice she's disappeared from my list of recommended friends again, so I check and confirm she's blo led me again, then I check IG and I'm blocked there too,

Why does she block then unblock then block again if I'm not bothering her,?
