New banlist leaks are probably fake

The leaked image says the new bans are

Pauper:

Mystic Sanctuary

Modern:
Arcum's Astrolabe

Boggart Harbinger

Pioneer:

Thassa's Oracle

Dig Through Time

Historic:

Burning-Tree Emissary

I don't believe this. Not being incredulous. I mean, I think it's fake. Pauper banned Mystic Sanctuary instead of Ghostly Flicker is just wrong. The only things that make a real amount of sense are Astrolabe, Oracle, and Dig. Sure, Harbinger is in a new combo deck but we still have Kiki-Resto/Exarch/Pestermite. There are even rumors Splinter Twin itself is being unbanned which is backed by the fact that Twin doubled in price recently.
