I agree with someone else in this thread, using Google Authenticator OTPs for 2FA would be best, and I'd require it for mods so this can't happen.

Actually, I have a sort of fix for this. When I had first played this, I never noticed speedup on my CRT monitor that normally does 85Hz, because my default monitor when I had launched the game was 60Hz, and I changed my default to my CRT while the game was open and then fullscreened, but when I launched later when my CRT was still default, it was playing much faster (I admit, the speed feels good :P). If you're doing a New Game+ where you can open the game before starting the run, you can make sure to set your default to a 60Hz monitor, then change it to your preferred not 60Hz monitor but not get the banned speedup from using a non-60Hz monitor.

EDIT: AFAICT, the bug isn't related to fullscreen, since I seem to get the speedup without even going fullscreen.
