This is because this title made me aware of a discreet bug because you can't have an HTML link `a` inside another `a`, which ends up happen if you put a link inside a title. The backslash prevents the link creation and fixes this.

We've also now forbade putting links like this in the title, and fixed various other related issues at around: https://github.com/ourbigbook/ourbigbook/commit/7b89f879409a415cc5bd0e35b4ee87837ea38473 

Thanks for breaking the site again :-)
