SysTweak: Misleading marketing via Speedtest.net

Had my lines upgraded to Fibre recently, and did a couple of speed tests on speedtest.net. Disappointingly, it seems speedtest.net are allowing misleading adverts such as the following;

These lead to;

hxxp://www.systweak.com/registryCleaner/newst/1/?xat=RC1;GB;L;1

Which leads to; hxxp://sr.systweak.com/speedtest/rcp/?x-at=RC1;GB;L;1 -> hxxp://sr.systweak.com/speedtest/rcp/rcpsetup/rcpsetupst_RC1_GB_L_1.exe

In this case, the advert is flash, and comes from;

hxxp://ads.ookla.com/www/delivery/ck.php?oaparams=2__bannerid=9314__zoneid=42__cb=26d3e6fd47__oadest=http%3A%2F%2Fwww.systweak.com%2FregistryCleaner%2Fnewst%2F1%2F%3Fxat%3DRC1%3BGB%3BL%3B1

hpHosts users won't see this advert as ads.ookla.com is already blocked by the hpHosts HOSTS file.
