Twitter would penalize accounts which contains "hateful imagery and display names" from December 18. The social media which aims to reduce hateful contents in its platform will also catch hold of people who use usernames, display name or profile bio to engage abusive behavior.

According to a report in ReCode late on Sunday, "for Twitter, the two new restrictions are attempts to combat rampant harassment and abuse on the site".

Twitter announced new guidelines covering abuse, hateful conduct, violence and physical harm in November.

Facing criticism over the years for its poor handling of "abuse", Twitter "updated" its rules in October and November, clarifying its policies on graphic violence, spam, and self-harm, among others.

The changes would revamp Twitter's policies surrounding online abuse.

The biggest updates on the platform include abusive behavior, self-harm, spam and related behaviors, graphic violence and adult content.

Twitter CEO Jack Dorsey has also announced plans to act more aggressively on violence and sexual abuse.

In an internal email which was obtained by Wired.com, Twitter's head of safety policy in October emailed members of its Trust and Safety Council on new rules to promote free speech and curb violence and sexual harassment.

"We hope our approach and upcoming changes, as well as our collaboration with the Trust and Safety Council, show how seriously we are rethinking our rules and how quickly we're moving to update our policies and how we enforce them," Twitter said.

"We will immediately and permanently suspend any account we identify as the original poster/source of non-consensual nudity and/or if a user makes it clear they are intentionally posting said content to harass their target," the email read.

"If the account appears to be dedicated to posting non-consensual nudity then we will suspend the entire account immediately," it added.

On hate symbols and imagery, it said: "At a high level, hateful imagery, hate symbols, etc will now be considered sensitive media (similar to how we handle and enforce adult content and graphic violence)".

On violent groups, Twitter said it will take enforcement action against organizations that use or have historically used violence as a means to advance their cause.
