People usually don't destroy evidence if there's nothing to hide. While this isn't always the case, it has been the case several times with pizzagate. Gianluca Longo was one of James Alefantis' facebook friends. ( https://archive.is/08yME ) He deleted his Facebook page sometime after James Alefantis deleted his. ( https://www.facebook.com/gianluca.longo.142 ) Not only does this seem like he was hiding something, it is more surprising considering that Longo is a public figure. Longo is a fashion expert that has worked at Vogue and Vanity Fair. He is currently an editor for W magazine and Cabana's. While he did delete his Facebook, he still has Twitter ( https://twitter.com/gianlucalongogg http://archive.is/JQs6Q ) and Instagram ( https://www.instagram.com/gianlucalongogg/ http://archive.is/DhLYk ) accounts. Through my digging, I have found several items of pizzagate interest. I will list them from what I think is most relevant to least relevant.

Story he wrote himself discussing going to Marina Abramovic's "art" exhibit -scroll down to "A Day at the Park" 

"I entered the big room, where people were wandering spaceless, some with eyes closed. Some gathered in the middle on a wooden platform as in ecstasy. In another room, Marina Abramovic herself was leading some chosen visitors to camp-beds and let them fall asleep, blanket on. And I was there, enjoying my time-less time, no phone, no camera, no stress."

When asked about causes he feels compassionate about, he said children in poverty. While not "proof", many of the people discussed in pizzagate have a public "concern" about under-privileged children.
