He knows he can't delete his most prominent images of pedophilia because it would confirm to the naive that he is hiding something. So he must keep them out in the open, but that also confirms he is guilty to those who become aware of what the motifs symbolize.

There are three images in particular confirming everything you need to know about this guy.

His own avatar on Instagram is an icon of pedophilia and child rape.

The image on the front page of Buck's fishing and camping has recurring pedophilia motifs.

The image on the front of Comet Ping Pong's facebook page is a recurring pedophilia motif.

All documented here, along with tons of other disturbing photos and imagery: https://voat.co/v/pizzagate/1469392

Again, he cannot delete this stuff. He must keep it in the open to maintain deniability.

That makes our job fairly easy: we simply raise awareness of what the imagery signifies in pedo communities.
