Its unfortunate the people broadcasting these spoiler images have no integrity. They claim to be such immeasurable super fans while disrespecting the creators left and right.
Marvel & Co would never encourage anyone receiving advanced copies, scans, pdfs, etc for whatever legitimate reason, only to have them set loose into the wilds of the website formerly known as Twitter.
These creators work hard to produce this material, only to have disgraceful "fans" disrespectfully plaster said content across the internet, out of the context and format it was intended, because "LOOK AT MEEEEEE"
Shameful.
