Heidipatrol

From Fandom wank wiki

The Heidipatrol, named after Heidi, exists in order to whitewash the Harry Potter fandom for posterity, usually as it regards Cassie Claire. Basically, they're a fandom version of the friend who comes into your place after you die and de-porns the place so that your loved ones don't find out what kind of pervert you really were.

However, though the wank material is suddenly gone, the splooge stains still remain all over the Internet.[1][2]
