LegendsVII claimed this is happening to Batman v Superman. He posted some interesting findings on the techniques used on Batman v Superman Dawn of Justice. Of all those twitter accounts that are spreading rumors and negativity around Batman v Superman Dawn of Justice, you'll see that they've been active a relatively long time and they've been tweeting random stuff off the Internet through a script that crawls for random text and garbles the text. Could this be the work of someone who hates WB/DC movies and wants desperately for it to fail or could it be Disney themselves? No one’s knows for sure, but if you want to read more about his finding read his post at reddit.
“These are bots maintained by a single entity. You pay for a service like this for the bots to follow an account (if you want to have lots of instant followers on the first go), or in this case, broadcast a particular message. So my informed guess is that someone hired whoever maintains these bots to keep on tweeting this message throughout a desired period of time. A service like this can cost as little as $5 on Fiverr but if this is something cloak and dagger, it's possible the person behind it hired the service through a referral, not a public site like Fiverr.”

Batman v Superman: Dawn of Justice hits theaters on March 25th, 2016.
Fearing the actions of a god-like super hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs.

Starring Henry Cavill, Ben Affleck, Gal Gadot, with Amy Adams, Laurence Fishburne, Diane Lane, Jesse Eisenberg, Jeremy Irons, and Holly Hunter, Batman v Superman: Dawn of Justice is directed by Zack Snyder, written by Chris Terrio from David S. Goyer's screenplay.
