I haven't had any, but when people were complaining about them I NoScripted all of the ads from VGC, only releasing VGChartz.com
In truth though I never had any porn ads showing up in the first place, I remember the last time people were complaining of Viruses I didn't have any either.... The time before that though I had 2 warnings (this was October/November and using IE)
