This is absolutely not true.
I will make that claim even more specific:
Less than 5% of the email:password combinations in the linkedin dump work today as email logins. “most” suggests a far higher success rate.
Also, with regard to your claim to have data about which passwords work. You should be aware that accessing someone's account with their username:password without permission (even a breached password) is likely illegal in the United States under the CFAA.
Most users that reuse passwords statistically did not rotate their passwords across all websites because most users that reuse passwords statistically do not rotate their passwords.
We aren't talking about the overall Linkedin userbase, just that specific subset that reuses passwords for secure services.
I have absolutely no idea what you mean.
>most users are probably still using the same password for their email as they used for LinkedIn in 2012.
Suggests that more than 50% of all users currently use their 2012 linkedin password as their email password, which is absolutely not true.
