Everyone - may that be friends of Kanye, celebrities, fan pages and members of the public - appears to be receiving follow backs from Kanye, including YEEZY MAFIA....so long as they share the same all-black avatar that he has.
Kanye hasn't stated a reason behind all of these follow-backs as of yet, though that has not stopped many fan pages showing love to Kanye for following back, as well as posting black squares mirroring his current profile picture.
It's also possible that this may be to do with the recent release of the "24" music video , with many of the fan pages posting promotional material from the video itself, as well as the "Donda Chant" video that was recently shown by Kanye.
For more updates on all things YEEZY, be sure to keep it locked to YM.
