Internet trolls are fast becoming an increasing problem across all social media platforms. An internet troll posts inflammatory, extraneous or off-topic messages online with the primary intent of provoking readers into an emotional response or otherwise causing controversy.

There have been a number of recent cases in the UK involving racist attacks against footballers via Twitter, resulting in both jail time and community orders. There have also been a number of individuals jailed in the UK for inciting rioting online. UK courts have adopted a zero tolerance approach to these cases, through the application of harsh penalties and long jail terms. It is hoped and expected that the Irish courts will follow this example.
