The MoviePass competitor Sinemia has been on a spree of terminating accounts over the past few days.

A half-dozen Sinemia subscribers have contacted Business Insider expressing dismay and confusion about their canceled accounts. Dozens more complained on Reddit.

Sinemia is sending a form letter to some of those affected, saying they are eligible for a refund "based on the difference between your payments to Sinemia and the cost of your ticket purchases."

In a statement to Business Insider, Sinemia said "a fter conducting a detailed fraud detection analysis, our system has detected fraudulent activities by a number of users whose memberships have been subsequently terminated due to violation of the Terms of Service."

The MoviePass competitor Sinemia terminated a slew of accounts over the past week, and some subscribers are furious.

Several people have contacted Business Insider over the past few days, saying their subscriptions to the movie-ticket service were canceled unfairly. Many others complained on a lengthy Reddit thread that started over the weekend and detailed complaints about account terminations.

Sinemia is sending a form letter to some of those affected. The letter lists a variety of possible reasons why their accounts were terminated, and says they are eligible for a refund "based on the difference between your payments to Sinemia and the cost of your ticket purchases," according to a copy of the letter viewed by Business Insider.

In a statement to Business Insider about the surge in cancellations, Sinemia said that "after conducting a detailed fraud detection analysis, our system has detected fraudulent activities by a number of users whose memberships have been subsequently terminated due to violation of the Terms of Service."

Sinemia continued: "If a member is terminated due to fraudulent activity, Sinemia is not required to provide a refund. Despite that, as an act of good faith, Sinemia has decided to provide full refunds of the difference between a member's 'membership payment and fees' and 'ticket purchases.'"

Sinemia has recently been hit with a string of complaints from customers, more than 200 of whom have contacted Business Insider since November, upset about various aspects of the service, including "misuse fees" and demands for copies of their IDs. Some customers filed a class-action lawsuit in November. It was amended in late February, alleging Sinemia ripped them off by introducing a new "processing fee."
