It appears that the site expects the Nielsen tracker to load, and so because it's content-blocked in strict mode, the page breaks.

It looks as though we may be able to get away with a simple shim which just defines window.nol_t as a function returning undefined (upon network requests for https://secure-nz.imrworldwide.com/v60.js)

I've just confirmed that the shim proposed above will fix this site.
