LONDON (AP) — Britain's press is urging social media users to tone down inappropriate criticism of Meghan, the Duchess of Sussex, and Catherine, the Duchess of Cambridge.

Palace officials have been seeking help from Instagram to monitor and remove offensive comments. Aides have been spending hours each week moderating comments on the official Palace Instagram account and removing racist and sexist content.

The Times newspaper reported Tuesday in an editorial called "Vile Abuse" that many of the comments made about Meghan and Kate are "too vicious to publish here and there have even been threats of violence."

Hello! magazine has launched a "kindness" campaign urging posters to think twice before posting abusive comments.

The magazine's royal correspondent Emily Nash says it is unacceptable to pit two women against each other.
