Social media platform Twitter told advertisers in an email that it will introduce new controls soon, possibly next week.

The new controls are part of Twitter’s efforts to reassure and re-attract advertisers who withdrew their ads from the platform since billionaire Elon Musk purchased it in October, amid reports from civil rights groups indicating that hate speech has increased since Musk’s acquisition and after reactivating several accounts that were banned or suspended.

Twitter also earns about 90 percent of its revenue from digital ad sales. Musk recently attributed a "massive decline in revenue" to pressure from civil rights groups on brands to stop advertising on Twitter.

A well-informed source said a Twitter representative stated in a call on Thursday with an advertising sector task force that the platform is considering having content moderators, many of whom are contractors through outsourcing companies, as part of the company’s workforce.

The source also added that the Twitter representative said that having content moderators as part of the company’s workforce would allow the platform to invest more in managing languages other than English.

The comments come after Ella Irwin, the new head of Trust and Safety, told Reuters that the platform will rely more heavily on automated content management. Irwin also said that recent layoffs at Twitter, which included 50 percent of the staff, did not severely affect the content management team and those working in sensitive areas such as child safety.

The email sent to advertisers on Thursday, viewed by Reuters, said that a revised version of Twitter’s subscription service called (Twitter Blue) would begin operating Friday.

According to the email, subscribing to this service will allow accounts to receive a verification badge. Individual accounts will get a blue verified checkmark, while gold and gray badges will be for company and government accounts.

The email added that the subscription price will be seven dollars per month on the web version and eleven dollars per month on Apple devices.

Twitter also told advertisers that it removed ads from accounts mentioned in an article published by The Washington Post on Tuesday, which referred to ads appearing on white nationalist accounts on Twitter.

Twitter told advertisers that it "will not reinstate accounts of bad actors, fake random accounts, and user accounts involved in criminal or illegal activities."

Twitter, which lost much of its communications team in the layoff campaign, did not respond to Reuters’ request for comment afterward.
