This may or may not be related to anything but several fans have sent word that something within the last few days, Sasha Banks unfollowed a bunch of accounts on Twitter.
Some of the names unfollowed included Bayley, Becky Lynch, The Usos, Seth Rollins, Roman Reigns, Vince McMahon and the official WWE account. Banks is currently following 6 accounts - Naomi, a couple of fansite accounts, John Cena, Tamina Snuka, and her cousin Snoop Dogg.
This happened before she walked out of tonight's Raw, thus forcing WWE to change tonight's main event. As noted earlier (via PWInsider), Banks was said to be unhappy with the creative for the main event. She was scheduled to be in a 6-Pack Challenge match to determine the number 1 contender for the Raw Women's Championship.
Vince McMahon reportedly did not back down on his plans and Banks then decided to leave the building. WWE quickly scripted a backstage segment with Becky Lynch and Adam Pearce to explain why the main event was changed. It was also noted that Naomi also walked out of the building with Banks.
