I posted a pic a while back when her cheeks looked to be at bursting point. I mentioned in my post at the time that one of them looked like a cyst.
Unfortunately the photo is no longer available.
I think I remember this!
I tried looking for it too when I wrote the post you quoted, but couldn't find it or another to illustrate the point. It seems every now and again her cheeks suddenly plump up, looking very natural, and this is why I think she isn't being honest when she says she doesn't use fillers. It's fits in with someone having them topped up.
