Bernie Sanders supporters are saying their Twitter account was “censored and locked down” after they criticized Hillary Clinton.

@GuerrillaDems — which goes by the name “Guerrilla Socialists” — was shut down Thursday.

RoseAnn DeMoro points out a Twitter executive recently held a fundraiser for Hillary, and alleges the two events are related.

The account, which Twitter claims was suspended “by mistake,” includes the hashtag #FeelTheBern, in honor of Bernie Sanders. “The Guerrilla Socialists Are Committed to the Enduring Fight Against the Corporate Ownership of Our American Democracy,” the account’s description reads.

@GuerrillaDems posted an email from Twitter, claiming the suspension was due to “automated systems that find and remove automated spam accounts in bulk. Unfortunately, it looks like your account got caught up in one of these spam groups by mistake.”

As of Friday morning, the account appeared to be reactivated and has resumed posting articles and videos critical of Clinton.
