Queen's University Belfast (QUB) and Belfast City Council are the latest organisations to stop using their X (formerly Twitter) accounts.
The platform has come under scrutiny after several investigations were launched over concerns that its AI tool Grok was being used to create sexualised images of real people.
Several organisations, including media outlets, locals councils, and charities have chosen to no longer post on the platform.
The Northern Ireland Council for Voluntary Action (Nicva) stopped posting on the platform in March last year, its Chief Executive Celine McStravick said X "really flew in the face" of all their values.
