sorry to re-bump this, but I'm now 100% sure of what this Jigsaw girl is doing, and it's probably worth sharing so you guys know what to say when you report her
every time you see her spar, you'll notice an alternate account is also in the spar arena - this is her secondary account, on a secondary device
she uses one device to connect through an extremely laggy VPN (by my experience in spars with her, I'd estimate around 800-1200ms on average)
she spars on this account, and then she watches the screen on her secondary device (the alternate account) - this is what allows her to delay like hell, yet still spar very responsively as if she has no delay at all, somehow knowing exactly where you are
I know pretty well how delay works and how to spar against it, but I was pretty confused when I sparred her a few weeks ago and saw how her delay behaved - assumed she was hacking in some way
this is definitely what she has been doing though, this is the 3rd or 4th time I've noticed random noob accounts following her around and "watching" her spar
I'll record proof if I see it again, but I doubt she'll do it around me and I know she reads these forums
some bits of proof in spoiler tag below
