Re: Passwords must be
I'd bet 90% have "Corbyn4PM" as their password and that includes some Tories. The rest probably "MayBot", "MayColdBitch", "AmberRudderless" or something that references "Cold" or "Bitch" in some combo or other. Any number they use will likely be the margin/number of votes they won by.
My suggestions are not meant to imply anything, regards my own point of view.
