I'm playing "a guy" who 4 months ago was a DGS 1k and has managed to make it to 4d ! This "guy" is not new to DGS, I've played "him" several times over the last couple of years and "he" was always around 1k.
I suspect foul play
It's not a big deal really, but this seems to me to be a new style of sandbagging and sandbagging in general hurts the game... IMO.
