The 31st was genuine if it wasn't already obvious, which means these aren't Chris because he was already in the motel on the 31st.

See how the date stamp for July 23rd is blurry but July 31st is crisp? That blurriness is anti-aliasing, which Photoshop automatically does on text when you're making it really small. You can disable it, but whoever was making the Photoshop did it without bothering to mess with the aliasing settings.
I knew the BDSM leak seemed dubious. It's a well done Photoshop but they got sloppy.
