Using that test for plusnet it shows only google servers as i am using 4.4.4.4
Are you sayingtheyplusnet don't know i am going to overclockers, as i would have only accessed it through this computer?
Should've mentioned this earlier, that test also isn't 100% accurate for determining a transparent DNS proxy because, based on your ISP's configuration, this may be easy or near impossible to detect.
With regard to keeping your logs, you have to trust what your ISP's policy says and their "intrepretation" of those requirements.
