This website uses a JSECoin script, which is blocked (The resource at “https://load.jsecoin.com/load/55093/ciberpeliculashd.net/0/0/” was blocked because content blocking is enabled.).

JSECoin offers advertising in addition to cryptomining: https://jsecoin.com/information-for-publishers/. This explains why blocking them also blocks the ad from displaying.
