Thanks for kickstarting this cheat sheet. My initial feedback is that we
should scrap 3.2 Defense Option 2: Multi-Step Login Process and 3.3 Defense
Option 3: IP blacklists. These defenses just don't work against this type
of attack. Even if they provide some defense against the most basic attacks
I feel it's misleading since it's trivial for an attacker to bypass these
defenses and real world attacks show that they regularly do.

Not meant as a bash on the overall cheat sheet. In fact I think I kicked
off this thread and am a big supporter of discussion here. But I think it's
good for us to avoid partial solutions that could give a false sense of

I like the other defenses. I think we also can add a few others which are
"additional identify verification" and "anti automation.
