Looking at MJ's post encouraging us to vote for some features, I noticed that the site has a side container displaying the initials of the persons who voted for a feature and hovering the mouse over the initials gives a floating notification of their email.
The problem(?) is that all of these emails are also embedded in the html:

So they could be picked up by webscrapers for spam. (Or, less likely, an obsessed fan might send hate mail to people who vote for rival features [:)])
Maybe Faithlife could just display the username instead?
