Yes they were, and they used what you personally blocked to better enable ads that would bypass their adblocker. They had some catchy name for it, I don't remember what. When they were exposed for their practices the privacy community did a mass uninstall. These features actually seem good, but I will never trust them again.
I tried to follow the link just to look at it, my firewall blocks it for 'tracking', I could bypass it but once bitten, twice shy.
