Social media giant Twitter has pledged to clamp down on trolls once and for all, according to reports.

Malicious users of the site are said to be hampering its efforts to be a frontrunner in the online news market and its European head, Bruce Daisley, told the Independent that Twitter was committed to cleansing the service as it enters its 10th year.

Twitter reportedly plans to introduce measures that spell out to trolls that their undesirable communications have an effect in the offline world, as well as the virtual space.

By making it clear that trolls' actions exist "in the real world" and encouraging victims to shop their abusers by publishing their names, it hopes to eradicate trolling and improve its brand.

Twitter has been valued at a reported $US17 billion ($A23.37 billion), a fraction of rival Facebook. The social media behemoth has over one billion users and is valued at $US290 billion.

A number of high-profile users, including celebrities and politicians, have closed their accounts after falling prey to trolls lurking among the site's 320 million users.
