Those ads you were seeing were not from Ezoic - the site hadn't been pushed onto the proxy fully yet, and traffic wasn't routing through Ezoic versions.
We've just turned the site onto the proxy fully, so you should start seeing Ezoic related ads within the next hour or so, provided you clear all caching for the site (both at Ezoic and elsewhere you have caching enabled). It's a good idea to clear your own browser cache as well.
