Weird @twitter accounts for Trump

On occasion I like to heckle @realDonaldTrump on @twitter. Something bizarre happens when you tweet trump enough with non-flattering information. I usually get a response from someone who seem s very angry and do nothing but send tweets to Trump. Many of these accounts only have a hand full of followers. I also notice they seem to have the same message, subtle racist undertones and anger / name calling. I have a theory that these are Trump campaign staffers trying to drum up chatter on twitter. Any one else notice this?
